Karen drove 504 miles in 8 hours.
At the same rate, how long would it take her to drive 819 miles?
--------------------
Karen drove 504 miles in 8 hours.
Find the speed.
d = r*t
r = d/t = 504 miles/8 hr
r = 63 mi/hr
===============
At the same rate, how long would it take her to drive 819 miles?
d = r*t (still)
t = d/r = 819 mi/63 mi/hr
t = 13 hours
