Question

The speed of two cars are in the ratio 4:5. If the speed of the first car is 20 km/hr, then what is the speed of the other car?

Answer 1

Answer:

Answer:

• Speed of the second car=25km/hr

Given:

• Speed of the first car=20Km/hr
• The speed of two cars are in the ratio=4:5

To find:

• Speed of the other car=?

Solution:

$let \: the \: speed \: of \: the \: first \: car = 4x$

$the \: speed \: of \: the \: second \: car = 5x$

According to the problem,

speed=distance/time

4x=20

x=20/4=5

So, Now speed of the other car,

$5x = 5(5) = 25$km/hr

So,Speed of the second car=25km/hr
