A can finish 2400m race in 1 minute 50 sec. While B can finish the same race in 2 minutes . By what distance A will defeat B in a race of 2400 m.
Answer & explanation
Correct answer: option 4
According to question ,
A runs a distance of 2400m in 1 minutes 50sec and B runs same distance in 2 minutes .
A beats B by 10 sec
Distance travelled by B in 2 minutes ( = 120 sec ) = 2400m
Distance travelled by B in 10 sec = \(\frac{2400\;×\;10}{120}\) = 200m
