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?

Distance from the beach to the park = 240 mi

Distance between beach and her house: x

Time from her house to the beach: 2.5 h

Her speed: x / 2.5

Distance between park and her house: 240 - x

Time from her house to the park: 1.5 h

Raul's speed = (240 - x) / 1.5

Same speed =>

x / 2.5 = (240 - x) 1.5

=> 1.5x = 2.5(240) - 2.5x

3.5x = 600

x = 171 m/h

171 m/h really fast!
