A can run 250 m in 25 sec and B in 30 sec. How many metres start can A give to B in a km race so that the race may end in a dead-heat?
Answer & Solution
Correct Answer:
Option
C
A → 250 m → 25 second
1000 m → 100 second
B → 2500 m → 30 second
1000 m → 120 second
B should run 20 ahead, i.e. 30
30 second → 250
20 second → $$\frac{{250 \times 20}}{{30}}$$
= 166.66
= 166.67 m
1000 m → 100 second
B → 2500 m → 30 second
1000 m → 120 second
B should run 20 ahead, i.e. 30
30 second → 250
20 second → $$\frac{{250 \times 20}}{{30}}$$
= 166.66
= 166.67 m
