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 1.05 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 2.65 m/s . It takes you 15.5 s to catch up and deliver the lost wallet. How far ahead of you was this person when you started running?

41.07 m

Explanation:

According to the data:

Velocity = 2.65 m/s

Time = 15.5 s

Now the formula to calculate the distance is

Distance = Velocity x Time

Distance = 2.65 x 15.5

Distance  = 41.07 meter

Kindly note that the person suddenly started to run at the velocity which is mentioned later that is 2.65 m/s.So the velocity given before is just ignored and we don't have to use any of the three equations of motion of kinematics.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
