Question

If someone ran 8 feet per second, how many mp/h are they going. Please explain. ?

Answer 1

First:  There are 60 x 60 = 3600 seconds per hour.

Second:  There are 5280 feet in a mile.

If someone runs 8 feet per second, he runs 8 x 3600 feet per hour.

8 x 3600 = 28,800 feet per hour

Since 5280 feet = 1 mile

1...........5280

---- =...-------------

y..........28,800

Cross multiply

y x 5280 = 28,800 miles per hour

y = 28,800/5280 miles = 5.4545 miles per hour   <<<<<

Answer 2

8 feet * 60 seconds * 60 minutes * 1 mile

--------------------------------------...

1 second * 1 minute * 1 hour * 5280 feet

(Everything is supposed to be lined up but you know how finicky yahoo is)

All of the units cancel out except for mile/hour

so the solution is about 5.4545454545 miles per hour.

Good luck to you !

Answer 3

8 feet/s * 1 mi / 5280 feet * 3600 s / h = 60/11 mi/h

60/11 is approx 5.4545 mph

Answer 4

Feet Per Second in Miles Per Hour

Feet X 60 X 60 / 5280ft

You take your Feet per second times 60 (secs in 1 minute) then times 60 again (minutes in one hour) which gives you feet traveled in 1 hour and to convert it into miles per hour you divide that number to feet in a mile which is 5280ft.

Answer 5

(8ft/sec) (1mile/5280ft)(3600sec/1hour)

5.45mph

make it a good day

Answer 6

1 mile = 5280 feet

1 hr. = 3600 sec.

  

how many miles in 8 ft?          8 / 5280 = 1.5 ( 10^-3) miles

how many hours in 1 sec?      1 / 3600 =  2.7 (10^-2} hours

divide:   miles / hour                             = 0.056  mph

Answer 7

1 mile = 5280 feet

8 feet = 8 / 5280 mile = 0.001515......15 miles

1 second = 1/3600 hours

8 ft/s

= (8/5280)miles / (1/3600)hours

= 5.45 mph
