Question

At 3:00 p.m., Jamie leaves her house and drives north to the beach. She arrives at 5:30 p.m. Also leaving at 3:00 p.m., her brother Raul leaves her house and drives south to a state park. He arrives at 4:30 p.m. The driving distance from the beach to the state park is 240 mi. Jamie and Raul drove at the same speed. What was their speed? Enter your answer in the box. mph

Answer 1

Jamie drove 2.5 hours and Raul drove 1.5 hours.  We know they traveled a total of 240 miles.  So rate x time = distance.

Jamie's distance = 2.5R (R being the speed she drove)
Raul's distance = 1.5R (R being the speed he drove)
R is the same for both since they drove the same speed.  The only thing different is time.

2.5R + 1.5R = 240
4R = 240
R = 240/4
R= 60
