A boy starts running on a straight line ...

A boy starts running on a straight line path with speed of 20km/h starting from same point. What is the position of the girl w.r.t. boy in 20 minutes?

Text Solution

AI Generated Solution

To solve the problem, we need to determine the position of the boy with respect to the girl after 20 minutes, given that the boy runs at a speed of 20 km/h and the girl is stationary. ### Step-by-Step Solution: 1. **Convert Time to Hours**: - The time given is 20 minutes. To work with the speed in km/h, we need to convert this time into hours. - \( 20 \text{ minutes} = \frac{20}{60} \text{ hours} = \frac{1}{3} \text{ hours} \). ...
