Question

Two stations a and b are 525 km apart. A train leaves station a from station b and at the same time another train leaves station b to
a. Both the trains meet 5 hours after they start moving. If the train starts from station a is 15 km/hr faster than the other one, then find the ratio between the speeds of both the trains?

Answer 1

Answer:

$3:4$

Explanation:

$A_{Distance}+B_{Distance}=525\\5\times A_{Speed} + 5\times (A_{Speed}+15)=525\\2\times A_{Speed} + 15 = 105\\A_{Speed}=45\\B_{Speed}=45+15=60\\Ratio = 45:60\\=3:4$
