aaron left at 9:15 to drive to his mountain cabin 110 miles away. He drove on the freeway until 10:45 and then he drove on the mountain road. He arrived at 11:15. His speed on the freeway was 3 times his speed on the mountain road. Find Aaron’s speed on the freeway and on the mountain road

1.5 hr on freeway     rate = 3x

   .5 hr on mt road     rate = x

 

rate * time = distance

 

1.5 (3x)    +   .5 x     = 110        solve for x  the mt road speed
