Question

If a car travels 10 m in 2 seconds, then the speed of the car is .

• A. $5m{s}^{-1}$
• B. $10m{s}^{-1}$
• C. $20m{s}^{-1}$

Answer 1

The correct option is A $5m{s}^{-1}$

Given, distance traveled by the car $=10m$ and the time taken $=2s$
We know, $speed=\frac{distancetraveled}{timetaken}=\frac{10}{2}=5m{s}^{-1}$.
