We will practice the questions given in the worksheet on expressing speed in different units. We know speed is equal to distance/time.

1. Find the speed in the following cases:

(i) Distance = 90 km, Time = 2 hours

(ii) Distance = 36000 m, Time = 24 seconds

(iii) Distance = 750 km, Time = 15 hours.

2. A student has to reach his school in 15 minutes. If the school is 800 metres way, at what speed should he walk?

3. A fox ran 1000 m in 5 minutes. Find its speed.

4. Sam and Tony went to Derek’s house in their cars. Sam
covered a distance of 11 km in 10 minutes. Tony covered a distance of 24 km in
20 minutes. Who drove faster?

5. Express each of the following speeds in metres per second:

(i) 36 km per hour

(ii) 72 km per hour

6. Express each of the following speeds in km per hour:

(i) 900 m per minute

(ii) 45 m per second

7. A man can cover 17 ½ km in 5 hours. Find his speed in

(i) m/min

(ii) m/sec

8. If the distance covered by a train is 360 km in 4 hours, find its speed.
