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
