A car bus travels at a speed of 45 km/h. How far will it travel in 36 minutes?

tensa zangetsu [6.8K]

Correct Question:

A car/bus travels at a speed of 45 km/h. How far will it travel in 36 minutes?

(Note- Corrected part is written in bold.)

Solution:

$\sf Speed = 45 \: km/h$

$\sf Time=36 \: mins$

$\sf = \frac{36}{60} \: hour \: (Since \: we \: know,1 \: hour \: = 30 \: mins$

$\sf = \frac{3}{5} \: hour$

$\sf \: Distance = Speed \times Time$

$\sf = \: 45 \times \frac{3}{5} \: km$

$\sf = \frac{45 \times 3}{5} \: km$

$\sf \: Distance=27 \: km$

Hence, a car/bus travels 27 km in 36 mins.
