Carla and Candice left from the same place at the same time and rode their bikes in the same direction along a straight road . Candice biked at an average speed that was threequarters of Carla's average speed. After 2 hours they were 28 miles apart. What was the average speed of Carla and Candice ?

they separated at 14 mi/hr
That speed was 1/4 of Carla's speed.
So, Carla rode at 56 mi/hr
Candice rode at 42 mi/hr
