What is the answer to our IQ question for October? Did you get it right? Read on to find out more!
Runner X and Runner Y jogged to and fro repeatedly along a straight path between point A and B. Runner X jogged at a uniform speed of 4 M/s and Runner Y jogged at a uniform speed of 6 M/s. They started jogging from opposite direction at the same time as shown:
They first met one another at point P. The second time they met each other was at point Q. Given the distance between P and Q is 160M, Find the distance between A and B.
One of the possible methods:
1.Runner X and Y ratio is 4:6 (between point A and B, X=4 parts, Y=6 parts)
2.The difference is 2 parts per distance (A to B), therefore to meet each other again,the total distance is twice (2 parts x 2)
3.Hence the difference is 4 parts, which is equal to 160M.
4. If 4parts=160m, then 1 part=40m
5. Since the total is 10 parts, the answer to the distance between A and B = 10 X 40 = 400M
The lucky winner will be announced soon. Stay tuned!
