Answer 1

They approach each other at 15 mph.
10 min = 1/6 hour
15 miles / hour * (1/6) hour = (15 /6 ) miles

Answer 2

they approach each other at 15/6 miles.

Answer 3

2.5 miles is when they approach each other.

Answer 4

Correct! Since they approached each other at a combined speed of 15 mph and met after 10 minutes (1/6 of an hour), the distance between them when they met would be:

Distance = Speed x Time
Distance = 15 mph x 1/6 hour
Distance = 2.5 miles

So, their home is 2.5 miles away from school.
