Problema Solution
Steve travels 5 times faster than Jill. Traveling in opposite directions, they are 663 miles apart after 6.5 hours. Find their rates of travel.
Answer provided by our tutors
Let speed of Jill=x miles/hr, So, speed of Steve=x+5
So, 663/(x+x+5)=6.5
663=13x+32.5
13x=663-32.5=630.5
13x=630.5
x=630.5/13=48.5
Rate of travel of jill=48.5 miles/hr
Rate of travel of Steve=53.5 miles/hr
