Question

A car takes $5hours$ to cover a distance of $400km.$ What is the average speed of the car?

Answer 1

Step 1: Given:

Distance, $S=400km$

Time, $t=5h$

Step 2: Formula used:

$Averagespeed\left(v_{av}\right)=totaldis\tan ce\left(S\right)/totaltime\left(t\right).$

Step 3: Final solution:

$$\begin{gathered} v_{av}=s/t \\ {v}_{av}=400/5 \\ {v}_{av}=80km/h \end{gathered}$$

Thus the average speed of the car is $80km/h$
