at 7a.m Gene left Austin and headed south at 10moh. At 8am Anne left from the same place and headed south on the smae road. if Anne was 60miles ahead by 3p.m on the same day, what was her speed?

Answer 1

Let s = Anne's speed.

 

8(10) = 80 miles travelled by Gene by 3:00.

 

7s = 80 + 60

7s = 140

s = 20
