Answer to Question #154776 in Physics for Shalize Dookie

Question

a child runs at a constant velocity of 0.90 m/s toward an ice cream truck which is parked 125 m away. If the ice cream truck is only parked for 3 minutes, will the child reach the ice cream truck in time? 

Answer 1

We can find the time that the child takes to clear the distance to the ice cream truck from the formula:

$$t=\dfrac{s}{v}=\dfrac{125\ m}{0.90\ \dfrac{m}{s}}=138.8\ s\cdot(\dfrac{1\ min}{60\ s})=2.3\ min.$$

As we can see, it takes 2.3 minutes for the child to reach the ice cream truck. Therefore, the child will reach the ice cream truck in time.

Answer:

$t=2.3\ min,$ the child will reach the ice cream truck in time.
