Given : Darla and her friend penny left their
office at the same time and began traveling
down the same road in the same direction. Darla
traveled at a speed of 65 mph while Penny drive
at 70 mph.
To find : How many hours was it before Penny
was 5 miles ahead of Darla?
Solution:
The formula used - Distance = Speed × Time
Darla traveled at a speed of 65 mph.
Penny drive at 70 mph.
Let x be the number of hours taken by both.
Distance covered by Darla is d1 = 65 x2 = 65.
Distance covered by Penny is da = 70 x2=
702

The number of hours was it before Penny was
5 miles ahead of Darla is 1 hour.
