Question

A bus travels 8km in the first quarter of an hour, 6km in second quarter and 16km in the third quarter. The average speed of the bus in km per hour over the entire journy?

Answer 1

40 km/hr.

Explanation:

The bus travels a total of
`8+6+16` km `= 30` km
in `3/4` of an hour.

`(30 " km")/(3/4 " hour")`
`color(white)("XXXX")` `= (4 xx 30 )/(3)` km/hr

`color(white)("XXXX")` `= 40` km/hr
