A bus starts from village A to `7:00` am and reaches village B at `8:30` am. If the discatnace between the villages A and B is 60 km. Find the average speed of the bus.

Text Solution

Verified by Experts

Here, distance (s) covered by the bus = 60 km.
Time (t) taken `= 8:30 - 7:00 am`
`= 1 (1)/(2)` hour`
`= (3)/(2)` hour
Average velocity `v = (s)/(t) = (60)/((3)/(2)) = 60 xx (2)/(3) = 40 km h ^(-1)`
The average speed of the bus is `40 km h ^(-1).`
