A can finish 1000m race in 3 min 10 sec. While B can finish the same race in 3 min 20 sec. By what distance A will defeat B in a race of 1000 m.
Answer & explanation
Correct answer: option 1
According to question ,
A runs a distance of 1000m in 3 minutes 10sec and B runs same distance in 3 minutes 20sec .
A beats B by 10 sec
Distance travelled by B in 3 minutes 20sec ( = 200 sec ) = 1000m
Distance travelled by B in 10 sec = \(\frac{1000\;×\;10}{200}\) = 50m
