In a 1000 m race, Arun reaches the final point in 56 seconds and Pradeep reaches in 70 seconds. By how much distance does Arun beat Pradeep?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 200 m
When Arun finishes (after 56 s), Pradeep has run for only 56 s at his own speed.
\( \displaystyle \text{Speed of Pradeep}=\frac{1000}{70}\ \text{m/s} \)
\( \displaystyle \text{Distance in 56 s}=\frac{1000}{70}\times 56 \)
\( =800\ \text{m} \)
So Arun beats Pradeep by 1000 − 800 = 200 m.
