Maria lives 1.85 miles east of the river. Dean lives 2.25 miles east of the river. The school is halfway between their homes. How Far East of the river is the school

Question

I need help on this question for a study packet

Answer 1

The way between their homes is;  2.25-1.85=0.4 miles so the school is at the middle of this distance

0.4/2=0.2 miles far east from Marias house and this is 1.85+0.2=2.05 far east from the river
