Question

A car travels from Boston to Hartford in 4 hours. The two cities are 240 kilometers apart. What was the average speed of the car during the trip? A. 4 km/hour B. 960 km/hour C. 60 km/hour

Answer 1

Average speed is 60 km/hour

Step-by-step explanation:

When we need to calculate average speed, we use this equation:

`V = (x_(f) - x_(o))/(t_(f) - t_(o))`

Where:
`x_(o) = 0 km` position at the beginning

`x_(f) = 240 km` at the end

`t_(o) = 0 hours`

`t_(f) = 4 hours`

Then:
`V = (240 km - 0 km)/(4 hours - 0 hours)`

`V = (240 km)/(4 hours)`

Finally V = 60 km/hour
