Question

7. Abus covers a certain distance in 3 hours 20 minutes at an average speed of 45 km per
hour. How much time will it take to cover the same distance at a speed of 50 km per
hour?
​

Answer 1

Speed = 45 km/h

Distance = 42×10/3

= 15 × 10 = 150 km

Now speed = 36 km/h

Distance = 150 km

Time = 150/36

= 25/6

4 hours 10 minutes.
