Answer 2

Given parameters:

Distance 1 = 319 miles

Time taken 1 = 6 hours

Distance 2 = 221 miles

Time taken 2 = 3 hours

Unknown:

Average speed = ?

To find the average speed we need find the total distance traveled and divided by the total time taken for the travel.

Speed is a scalar quantity that expresses the distance covered per unit of time.

Mathematically;

Average speed =
`(Total distance )/(Total time taken )`

=
`(distance 1 + distance 2)/(time taken 1 + time taken 2)`

=
`(319 + 221)/(6 + 3)`

= 60miles/hr

The average speed of the bus is 60miles/hr
