A takes 10 minutes more than B in covering a certain distance. If their speeds are in the ratio of 3 : 4, then what is the time taken by B to cover the same distance?
Answer & explanation
Correct answer: option 2
Speed = \(\frac{DIstance}{Time}\)
We know ,
Speed is inversely proportional to Time
Ratio of , A : B
Speed 3 : 4
Time 4 : 3
According to question ,
( 4 - 3)R = 1R = 10 minutes
3R = 3 × 10 = 30 minutes
So , time taken by B is 30 minutes
