Distance Time
A car moves with a speed of 40 km/h for 15 minutes and then with a
speed of 60 km/h for the next 15 minutes. The total distance covered by
the car is:
(i) 100 km (ii) 25 km
(iii) 15 km (iv) 10 km
Show the shape of the distance-time graph for the motion in the
following cases:
(i) A car moving with a constant speed.
(ii) A car parked on a side road.
Salma takes 15 minutes from her house to reach her school on a
bicycle. If the bicycle has a speed of 2 m/s, calculate the distance

odometer reading has changed to 57336.0 km? Calculate the speed of
the car in km/min during this time. Express the speed in km/h also.
The distance between two stations is 240 km. A train takes 4 hours to
