Question

Abus driver drives at a speed of 75 kms per hour for the first two hours and at the
speed of 70 kms per hour for the next 3 hours. What was his average speed?​

Answer 1

Speed = 75km/h

Time taken = 2 hrs

We know, distance = Speed × Time

= 75×2= 150 km

So, distance for first case is 150km

Speed = 70km/h

Time taken = 3 hrs

We know, distance = speed × time

So, 70×3= 210km

So, Distance for 2nd case is 210km

We know,

average speed = total distance /total time

Total distance= 210+150= 360km

Total time = 2+3= 5hrs

Now, average speed = 360km/5hrs= 72km/h

Therefore, Average speed of bus driver is 72km/h
