A car is moving at the uniform
Speed of 45 km/h
a) How fou will it travel in 5 hours
b) the distance covered
in 40 minutes.
​

Answer 1

Answer :-

Given :-

Speed of car = 45 km/h

a) How far will it travel in 5 hours :-

So , Time = 5 hours

By using ,

$speed \: = \frac{distance}{time}$

$45 \: = \frac{distance}{5}$

$distance \: = 225 \: km$

So , car will travel 225 km in 5 hours.

b) the distance covered in 40 minutes :-

Now , time = 40 minutes

So , we have to convert speed in m/s

Note :- For converting in m/s we have to multiply the given speed by 5/18.

$= 45 \: \times \frac{5}{18} = 12.5 \: m/s$

Again By using Formula ,

$speed \: = \frac{distance}{time}$

$12.5 \: = \frac{distance}{40}$

$distance \: = 500 \: m$

So , 500 m distance is covered in 40 minutes.
