Question

An automobile travels 130 km in 2.5 hours and 150 km in 3.5 hours. What is its average

speed over the entire distance traveled?

Answer 1

46.67
`(km)/(hr)`

Step-by-step explanation:

If the car goes 130 km in 2.5 hours and 150 km in 3.5 hours, the total distance traveled is 280 km. That distance was traveled in 6.0 total hours.

The average speed can be found by:

`v=(d)/(t)\\d=280km\\t=6.0hr\\v=(280km)/(6.0hr)\\v=46.67(km)/(hr)`
