Question

You are walking down a straight path in a park and notice there is another person walking some distance ahead of you. The distance between the two of you remains the same, so you deduce that you are walking at the same speed of 1.25 m/s. Suddenly, you notice a wallet on the ground. You pick it up and realize it belongs to the person in front of you. To catch up, you start running at a speed of 2.75 m/s. It takes you 12.5 s to catch up and deliver the lost wallet. How far ahead of you was this person when you started running

Answer 1

18.8m

Step-by-step explanation:

This implies calculating the relative speed first then find the distance d

So

relative speed = 2.75- 1.25 = 1.5 m/s

So assume the distance between them to be say d

so, d/1.5= 12.5

d = 18.8m
