A is 1\(\frac{2}{5}\) times faster than B. A gives 80 mtr start to B in a race. Find the total distance of race if both finish the race at the same time.
Answer & explanation
Correct answer: option 4
A : B
Speed : 7 : 5
Distance: 7 : 5 ⇒ 2R (start)
2R = 80m,
1R = 40m
7R = 280m = Total distance of race
