Question

if a car covers a distance of 75km in one hour, find the distance covered in 45 min.​

Answer 1

Given:-

A car covers 75 km in 1 hour.

To Find:-

The distance that it will cover in 45 minutes.

Solution:-

1 hour = 75 km

1 minute = $\sf\dfrac{75}{60}$

In 45 minutes = $\sf\dfrac{75}{60} \times 45$

$= \sf {\cancel\dfrac{75}{60} \times {\cancel {45}}}$

$= \sf\dfrac{75}{4} \times 3$

$\sf= 56.2 \: km$

∴ The car will cover 56.2 km in 45 minutes. ✔

${\sf Speed \: = \dfrac{Distance}{Time}}$

$\sf {Distance = Speed \: × Time }$

To find time on cars:-

$\sf Time =\dfrac{Distance}{Speed}$

To find time on Trains:-

$\sf Time = \dfrac{Length\: of\; the \; train}{Speed\; of\;the\;train}$
