The speed of two cars A & B is in ratio 5 : 6 . Find ratio of time taken by them .
Answer & explanation
Correct answer: option 2
Distance = Speed × Time
& Speed = \(\frac{Distance}{Time}\)
If distance is same , The ratio of the speeds of two objects is inversely proportional to the ratio of the time by them to cover the same distance.
Ratio of speed of car A & B = 5 : 6
Let speed of car A = 5x & Speed of car B = 6x
And Distance = D
A : B
Speed 5 : 6
Time \(\frac{D}{5x}\) : \(\frac{D}{6x}\)
Time \(\frac{1}{5}\) : \(\frac{1}{6}\)
6 : 5
