The ratio of speed of A and B is 3 : 7 and A loses the race by 360 m, then find the length of the race.
Answer & explanation
Correct answer: option 1
The time is same for A and B.
Therefore, Distance ∝ Speed,
A : B
Speed 3 : 7
Distance 3 : 7 Difference = 4R
4R = 360
1R = 90
The length of race = distance covered by B = 7 × 90 = 630 m
