Two cyclists start from the middle of a 200m track and move in opposite directions towards the end of the track at 5m/s and 10m/s respectively. At the time when a cyclist first reaches the end, both cyclists turn around and start moving towards each other with their initial speeds. During this motion, a fly moves at a speed of 17 m/s, between the 2 cyclists, landing on one cyclist and then moving to the next continuously. How much distance has the fly covered when the two cyclists meet again?
Answers
Given : Two cyclists start from the middle of a 200m track and move in opposite directions towards the end of the track at 5m/s and 10m/s respectively.
To find : distance has the fly covered when the two cyclists meet again?
Solution:
Distance between cyclist & track end = 200/2 = 100 m
Cyclist with more speed 10m/s will reach end first
time taken = 100/10 = 10 sec
Distance covered by other cyclist in 10 seconds = 10 * 5 = 50 m
Distance between cyclist = 100 + 50 = 150 m
Time taken to meet each other = 150/(10 + 5) = 10 sec
Total time = 10 + 10 = 20 secs
Speed of fly = 17 m/s
Distance Covered by fly = 17 * 20 = 340 m
Distance Covered by fly = 340 m
