Question

A car travels 450km in 4 hours. Calculate the average speed of a car in km/hr. (Round answer to one decimal place)

Answer 1

We can find the average speed of the car from the formula:

$$v = \dfrac{s}{t} = \dfrac{450 \ km}{4 \ h} = 112.5 \ \dfrac{km}{h}.$$

Answer:

$v = 112.5 \ \dfrac{km}{h}.$
