For instance, if you travel one mile in 51 seconds, how fast are you travelling?

An hour has 60*60=3600 sec.
So:
51sec > 1 mile
3600 sec > x?
x=3600/51=70.58
You’re travelling with a speed of 70 miles per hour.
for your example it’s:
(1mile / 51s) x (3600s/1h) = 70.58miles per hour
=)
Dimensional Analysis is the best way to go:
[1mile/51seconds] * [(60*60) seconds/1hour]
The seconds cancel out and you get miles per hour.
so: (1/51) * (60/1) = 70.588235294117647058823529411765
Without all the details:
Miles Per Hour = 70.58
Kilometers Per Hour = 112.93
Luckily for you I am learning about this in school. To find out how fast you’re going you need to do 4 simple steps. STEP 1. List your knowns and unknowns. You have 51 sec and 1 mile, but you don’t know what the speed is. STEP 2. Make the equation. Since you don’t know speed it is S=D/T. Very simple. STEP 3. Make the problem. Speed=1m/51sec. Step 4. Solve the problem. (make sure you use decimals not fractions, also you should round your answer to the hundreths or tenths place) Once you work out the math it equals Speed=.0196078431m/sec. To make it simpler its Speed=.02m/sec. To find out how fast you are going in m/h you multiply .02×60 to make minutes (1.2) then multiply again by 60 to make an hour (1.2×60=72). Then you have it, youre speed is 72m/h.Looks long but it helps. My teacher said if you did this problem right it would be right 99.9% of the time. He even backed it w/ his moneyback garuntee. Unfortunately, we didn’t pay him anything! : )
If you gone 1 mile in a minute your going 60 miles an hour(1*60=60(60minute in an hour))so now you put the 51 seconds over the 60 seconds in a minute 51/60 = 1 9/50(1.18)multiply by 60 1.18*60 =70.8miles and hour. good luck
3600 / 51 = 70.5 mph
60 sec. in a minute and 60 minutes in an hour so…
60 x 60 = 3600 seconds in an hour so…
(3600 divided by 51 equals 70.5)
It’s simple: x = vt
So if 1mile/51 sec. = .019607843
and 60sec./1min. = 60
and 60 min/1 hr. =60
then .019607843 * 60 * 60 = 70.58823529 mph
Or to simplify 1/51 * 3600 = 70.58823529 mph
Your rate is 1 mile/51 sec
1 hr = 3600 sec
or
3600 sec/1 hr = 1
Multiply your rate by this form of 1
(1 hr/51 sec)(3600 sec/1 hr) = 70.58 mi/hr
use fraction (ratios) to convert seconds to hours
1 mile/51 seconds * 60 sec/1min. * 60 min/1 hour
so, the answer is 3600/51 miles/hr.
70.59 m/hr (approx.)
(1/51) times (3600 sec)/ hour = 70.59 miles per hour (approx.)
Multply 51 by 60 to convert to miles per minute which is 3060, then multiply by 60 again to convert into miles per hour which is 183600.
To shorten it into one step multiply 51 by 3600 because 60 times 60 is 3600.
Hope I helped.
1mil/51sec X 60sec/1min x 60min /1 hour
these are just timesing by 1
so sec and min get crossed out so 3600min/51hour so its about 70.5mil / hour
MPH = 3600/t (t is time in seconds to travel one mile)
MPH = 3600/51 = 70.59 MPH
light speed. you couldnt do that with a car no way . you would have to be clark kent or the flash or something.
there are 60 seconds per minute 60 minutes an hour that makes 3600 seconds in an hour now divide by the seconds its 70.7 something an hour
x = vt
1mile = v (51s)
v = .0196078431 mile/sec.
this doesn’t make any sense at all,so i will convert to mi/hr
1mile/51s * (60s/1min) * (60min/1hr) = 70.6miles/hr
Distance = Rate x Time
Rate = Distance / Time
Distance = 1 mile
Time = 51 seconds
Change 51 seconds to minutes = 51/60 =0.85 minutes
Change minutes into hours .85 minutes / 60 minutes /hour =
0.0142 hours
Rate = 1 mile / 0.0142 hour
Rate = 70.42 miles per hour
