Answer 1

Let's convert these fractions to decimals.

They start at the 2.4 marker and end at the 8.1 marker

8.1 - 2.4 = 5.7 miles

5.7 / 3 = 1.9 hours

10 + 1.9 = 11.9 which is before noon.

Answer 2

Yo, do you go to Pines? I had the same homework :0

11.9 and that means that they will be there by noon or before noon
