Given:
Speed of car, v = 180 km/hr = 50 m/s
Time, t = 10 h
Let the rest distance be L0.
Apparent distance is given by
Apparent distance, L' = 10 × 180 = 1800 km = 18 × 105 m
Now,
Thus, the rest distance is 25 nm more than 1800 km.
(b) Let the time taken by the car to cover the distance in the road frame be t. Then,
