*Tick (✓) the correct answer:*

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

(a) 25 km

(b) 15 km

(c) 30 km

(d) 20 km

**Solution:**

(a) 25 km

Let *x* km be the required distance.

Now, 1 h = 60 min

Distance (in km) | 75 | |

Time (in min) | 60 | 20 |

Less distance will be covered in less time

Now, $\frac{75}{60}=\frac{x}{20}$

$\Rightarrow x=\frac{75 \times 20}{60}$

$\Rightarrow x=25 \mathrm{~km}$
