Question

Q9. If a car covers a distance of 75 km in one hour , find the distance covered
by it in 45 minutes.​

Answer 1

Given:

• distance covered by the car = 75km

• time taken by the car to cover the distance = 1hr

To Find:

distance covered by the car in 45 minutes

Solution:

$➙$car speed = 75km per hour

$➙$time = $\tt{45mins \: = \frac{45}{60} hours}$

$➙$Distance = to be found in km

As we know that:

$\tt\underline\red{distance = speed × time}$

$\tt{\implies \: distance \: = 75km/hr \times \frac{45}{60} hours}$

$\tt{ \implies \: distance \: = 75 \times \frac{45}{60}}$

$\tt {\implies \: distance = 75 \times \frac{3}{4}}$

$\tt {\implies \: distance \: = \frac{225}{4} }$

$\implies\tt\underline\purple { distance = 56.25km}$

Hence:

• the distance covered by the car in 45 minutes is 56.25 kilometres
