Question

A and B are 110 km apart from each other and they started horse riding forwards each other at same time at speed of 20k/h and 24k/h.After how many hours of riding they will be distance of of 22km​

Answer 1

Answer:

Time taken = 2 hours.

Step-by-step explanation:

Given -

Distance between A and B = 110 km.

Speed of A = 20 km/hr.

Speed of B = 24 km/hr.

Now,

Time taken by them to be at a distance of 22 km from each other is -

$\bigstar\;\boxed{\sf Time=\dfrac{Distance\ travelled}{Speed\ of\ approach}}}$

It implies,

Distance between them = Total distance - Distance travelled.

So,

=> 22 = 110 - Distance travelled.

Distance travelled = 88 km.

Speed of Approach = 20 + 24 = 44 km/hr.

As we know,

$\bigstar\;\boxed{\sf Time=\dfrac{Distance\ travelled}{Speed\ of\ approach}}}$

So,

=> $\sf \dfrac{88}{44}$

=> 2 hr.

Therefore,

Time taken = 2 hours.
