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, 
Jeff runs one lap in 2 minutes and 15 seconds = 135 s
Speed of Jeff, 
Let t be the time when Jeff run one extra lap,
That is
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

Answer:
They are 192 km apart.
Step-by-step explanation:
? = unknown value
We can use the equation
? km = ?cm * 8
Or ratio
1/8 (What do you multiply 1 by to get to 8? 8. 1 is how many cm there are so if there are 24 cm then we multiply that by 8 as well.)
We have to multiply 24cm by 8 because of the ratio 1:8, 24 times 8 is 192.
You could do 150 + 30a = t. shes already paying the 150, but its 30 per appointment so a would represent how many appointments she brought Pedro to. That altogether would equal the total or t.
