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

Answer: 171 m/h .... really fast!
