Question

The speeds of three cars are in the ratio of 2 : 3 : 5 Find the ratio of the time taken by the above cars to travel the same distance.​

Answer 1

Answer:

15 : 10 : 6

Step-by-step explanation:

Distance = speed × time

2×t1 = 3×t2 = 5×t3 (since the distance covered by three cars is same)

LCM of 2 , 3 , 5 is 30

2 × 3 × 5 = 30

2×(3×5) = 3×(2×5) = 5×(3×2)

2×15 = 3×10 = 5×6

t1 = 15 , t2 = 10 , t3 = 6

Therefore the ratio of the time taken by th cars is

15 : 10 : 6
