Two trains A and B started running towards the same destination station 'Y', with A already 20 km ahead
of B. When train B reaches station Y which is 300 km from him, train A is still 10 km away from the
destination. Then, what will be the ratio of the speed of train A to train B?

Answers
Answer:
9:10
Step-by-step explanation:
Total distance covered by Train B = 300 km
Total distance covered by Train A = 300 - {20 + 10}
= 270 km
Ratio of Train A to Train B is
270 : 300 = 9 : 10.
Answer:
If two train A and B running in same direction where A was 20 km ahead already and A was 10 km away from destination when B reached the destination, then the ratio of speed of A to B is 9:10
Step-by-step explanation:
Here given that total distance to the station is 300km
Here, B travels 300 km to reach the destination Y
So, total distance traveled by B is 300 km
While A was already 20 km ahead and also A didn't travel 10 km when B reached Y
So, the total distance traveled by A = 300-(20+10)= 300-30 = 270 km
Here, the time taken is same,
So ratio of speeds of A to B = 270/300 = 9/10
So the ratio of speed of A to B is 9:10
