Question

A car traveled a distance of $100km$ in $2hours$. Find the average speed of the car.

• A. $50km{h}^{-1}$
• B. $10km{h}^{-1}$
• C. $20km{h}^{-1}$
• D. $30km{h}^{-1}$

Answer 1

The correct option is A

$50km{h}^{-1}$

$\text{Average speed}=\frac{\text{Total distance}}{\text{Total time}}$
$\text{Average speed}=\frac{100}{2}$
$\text{Average speed}={50kmh}^{-1}$
