Answer:

Time taken to cover 1 km = 1/60 hour.

Time taken to cover 300 km = 1/60 × 300 hour.

= 5 hours.

Therefore, time taken to cover 300 km is 5 hours.

2. A man runs at the speed of 15 km per hour. How much time will he take to cover 750 metres?

Speed = 15 km per hour

Distance = 750 metres = 750/1000 km = ¾ km

Time = distance/speed = (3/4 ÷ 15) km

= (3/4 × 1/15) hr

= 1/20 hr

= 1/20 × 60 min = 3 minutes.

3. How much time will be taken to cover a distance of 450 km at a speed of 50 km per hour?

Solution:

Time taken to cover 50 km = 1 hour.

Time taken to cover 1 km = 1/50 hour.

Time taken to cover 450 km = 1/50 × 450 hour.

= 5 hours.

Therefore, time taken to cover 450 km is 9 hours.

4. A motorised rickshaw covers a distance of 150 km at a speed of 30 km/hour. Find the time taken to cover this distance.

Time = distance/speed

Time = 150 km/(30 km/hour)

= (150 km/30 km) × hour

= 5 hours.
