Question

Two people start walking at the same time in the same direction. One person walks at 8 mph and the other

person walks at 3 mph. In how many hours will they be 1.25 miles apart?

Answer 1

0.25hours

Explanation:

Data

speed v1=8mph

speed v2=3mph

distance= 1.25

time t=?

speed= distance/time

distance=speed*time

1.25=8*t-3*t

1.25=8t-3t

1.25=5t

t=1.25/5

t=0.25hours

In minutes it is 15min
