A can finish 3800m race in 3 min . While B can finish the same race in 3 min 10 sec. By what distance A will defeat B in a race of 3800 m.
Answer & explanation
Correct answer: option 3
According to question ,
A runs a distance of 3800m in 3 minutes and B runs same distance in 3 minutes 10sec .
A beats B by 10 sec
Distance travelled by B in 3 minutes 10sec ( = 190 sec ) = 3800m
Distance travelled by B in 10 sec = \(\frac{3800\;×\;10}{190}\) = 200m
