Answer 1

Dear Faiyaj,

◆ Answer -

vA / vB = 17 / 19

● Explaination -

# Given -

t1 = 361 hrs

t2 = 289 hrs

# Solution -

Let vA & vB be speed of A & B respectively. Consider tA & tB be their respective time to reach the destination.

Speed of A & speed of B are related by formula -

vA / vB = √tB / √tA

vA / vB = √289 / √361

vA / vB = 17 / 19

Hope this is useful..
