Question

A car is travelling a uniform speed of $75km/hr$. How much distance will it cover in $20$ minutes?

• A. $25km$
• B. $15km$
• C. $30km$
• D. $20km$

Answer 1

The correct option is A $25km$

We use the formula $Speed=\frac{Distance}{Time}$

Let us consider the distance be $xkm$

Then time $=\frac{20}{60}hr=\frac{1}{3}hr$

$\Rightarrow S=\frac{D}{T}$

$\Rightarrow 75=\frac{x}{1/3}$

$\Rightarrow x=75\times \frac{1}{3}$

$\Rightarrow x=25$

$\therefore$ the car will cover $25km$.
