Answer:
6 minutes
Step-by-step explanation:
Given
Leo = 36 sec / rev
Stan = 40 sec/rev
Required
Determine the time (in minutes) they'll meet again
We start by getting the multiples of 36 and 40 uptil we get a common multiple.
Leo: 36 = 36, 72, 108, 144, 180, 216, 252, 288, 324, 360, .....
Stan: 40 = 40, 80, 120, 160, 200, 240, 280, 320, 360....
From above, the common multiple is:
Common Multiple = 360
This means that they'll meet at 360 seconds
Convert to minutes
360 sec = 360/60 mins
360 Seca = 6 mins
Hence,it will take them 6 minutes to meet again at the starting point
