Answer:
Step-by-step explanation:
Here, we want to get the specific time at which they passed each other again in the pool
From the question, they both maintained same turning time and did not lose speed
What this means is that the time it takes for both to pass each other will be constant at a minute and a half
Thus, the time taken to move from the edge of the pool to the point at which they meet will be 1 minute and 30 seconds
Thus, a minute and half will pass to get to the edge of the pool, then another a minute nd half to meet again
This makes a total of 3 "a minute and a half"
