<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}--> A racing car covers a distance of $500\text{m}$ in $10\text{s}$. What is the speed of the car?

• A. $20\text{m/s}$
• B. $50\text{m/s}$
• C. $10\text{m/s}$
• D. None of these

Answer 1

The correct option is B $50\text{m/s}$

Distance covered in $10\text{s}$ = $500\text{m}$
So, distance covered in $1\text{s}$ = $\frac{500}{10}\text{m}=50\text{m}$
$\therefore$ Speed of the car=$50\text{m/s}$
