How far can a person run in 15 minutes if they can run 2 miles per hour?

if a person can run 2 miles per hour which means 60 mins

60x=15×2

60×=30

×=30/60

×=0.5miles

so a person can run 0.5 miles in 15 minutes

which means 804.67 meters in 15 minutes

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
