Answer 1

r < 37 or r ≥ 42

Explanation:

the route, r?

than 37 minutes

she leaves after 7:00

then r= 37 or r ≥ 42

or

r < 37 or r ≥ 42

Answer 2

8:55 am.

Explanation:

First we find the least Common Multiple of 25 and 35.

25 = 5 * 5

35 = 5 * 7

The LCM = 5 * 5 * 7 = 175 minutes

or 2 hours 55 minutes.

So the required time is 8:55 am.
