Steve want to catch up to Cami, a girl he likes. If he is jogging at 8 m/s and she is walking at 1 m/s. How long will it take him to reach her if they are 10 meters apart?

1) if they are moving away from each other it will take 1.43 secs

2) if they are moving towards each other then it will take 1.11 secs

Explanation:

Distance between them is 10 m

Speed (if they are moving towards each other) = distance/time

time = 10/8+1

time = distance / speed = 10/9 = 1.11 secs

if they are moving away from each other than it will take

time = 10/8-1 = 10/7 = 1.43 secs
