how do i calculate my average MPH?

Question

say if i ran 100 feet in 15 seconds, how would i find out my miles per hour.

Answer 1

Convert feet to miles.
Convert seconds to hours.
Take the number of miles and divide by the number of hours.
Conversions that you will need for this problem include:
5280 feet = 1 mile
60 seconds = 1 minute
60 minutes = 1 hour

Answer 2

The total miles divided by the total time will equal the MPH.

M/T = MPH

You would have to convert the feet into miles (5280 ft in a mile) and then convert the seconds into hrs (60 x 60).

In your example: 100 ft is 100/5280 miles
and 15 seconds is 15/60 (1/4) of a minute or 1/240 hr.

You went 100/5280 miles in 1/240 hrs

or 5/264 miles in 1/240 hrs.

Divide your fractions to obtain the decimal value and we have:

let X = MPH then we have .0192/.0042=X

which will give us X= 4.57 MPH

Not very quick.....you'd never steal second base at that rate!

Answer 4

It's much easier to calculate the average MPH by standing still rather than running. The answer is then 0 mph.

Answer 5

100 ft = 100/5280 mi
15s = 15/3600 hr

so mph = 1500/(3600*5280)
= 15/(36*5280)
= 5/(12*5280)
= 1/(12*1056)
= 1/12672 mph

Answer 6

1 mile = 5280 ft
1 hour = 3600 sec

so

100 ft / 15 sec x 1 mile/ 5280 ft X 3600 sec / hr = 4.55 miles / hr

you cancell ft and sec

Answer 7

I agree with LeAnne

distance in feet * 3600 / time in seconds * 5280

Answer 8

Divide 2.90 miles by 45 min.

Answer 9

100/15 this will equal the answer.

Answer 10

(100feet/15sec)*(3600sec/1hr)*(1M/5280ft)=4.54 mph.
