a man cover a total distance of 900km in his motor bike with an avareage speed of 45km/h how much time does it take
Answers
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.
