A car left a city travelling uniformly at a speed of 80 km/h. It was followed 1.5 hours later by a motorcycle whose speed was 100 km/h. How much time elapsed after the car left the city before the motorcycle caught up with it? Where did this take place? Plot the graph.

Text Solution

Verified by Experts

The correct Answer is:
t = 7.5 h; x = 600 km.
The graph is shown in Fig. The law of motion is `x_(1)=80t, x_(2)= 120 (t-1.5)`.
