The question for the day is from the topic of Races.
- Three runners A, B and C run a race, with runner A finishing 12 meters ahead of runner B and
18 meters ahead of runner C, while runner B finishes 8 meters ahead of runner C. Each runner travels the entire distance at a constant speed.
What was the length of the race?
| (1) |
36 meters |
| |
(2) |
48 meters |
| (3) |
60 meters |
| |
(4) |
72 meters |
Correct Answer - (2)
Solution:
Go from answer choices
Let the race be of length 48 meters
So when A runs 48m B run 36m and C runs 30m
Ratio of distance covered by B : C = 6 : 5
So when B covers 48m C would have covered 40m => B can give C a start of 8m.
