Answer:

At 8:52:30 am they will be side-by-side again

Step-by-step explanation:

Let s be the distance ran in one 1 lap.

Here Jeff runs one extra lap compared to Mandy for coming side by side again.

Mandy runs one lap in 2 minutes and 30 seconds = 150 s

Speed of Mandy, $=\frac{s}{150}$

Jeff runs one lap in 2 minutes and 15 seconds = 135 s

Speed of Jeff, $=\frac{s}{135}$

Let t be the time when Jeff run one extra lap,

That is

$t\times \frac{s}{135}-t\times \frac{s}{150}=s\\\\t\left ( \frac{1}{135}-\frac{1}{150}\right )=1\\\\t\times \frac{15}{135\times 150}=1\\\\t=1350s$

So after 1350 seconds Jeff comes side by side to Mandy,

They both start at 8:30 am

1350 s = 22.5 minutes = 22 minutes 30 seconds

Time = 8:52:30 am
