Carl averaged 2 m miles per hour on a trip that took him h hours. If Ruth made the same trip in \frac{2}{3} h hours, what was her average speed in miles per hour?

Explanation	Calculations	Help
$We first use the distance formula to find the total distance of the trip in terms of the given variables.$	$D = (2 m) \times h$	Theory & Tactics Method Card TRANS3-C Click to view full details
$We then express Ruth's average speed as the distance divided by her travel time.$	$v = \frac{D}{\frac{2}{3} h}$	Theory & Tactics Method Card TRANS3-C Click to view full details
$Substitute D = 2 mh and simplify to find v .$	$v = \frac{3 D}{2 h} = \frac{3 ( 2 mh )}{2 h} = 3 m$
