First, calculate the speed she was driving on. Speed=distance/time distance=221.05 miles Time=4 hours Units are important 221.05/4 =55.263 mph Now it says at the same speed she's driving 83 miles more. You can use a proportion to solve this. 55.263 miles/1 hour = 83 miles/ x hours Cross multiply 83=55.263x x=1.502 1.502 is closest to option C, 1.5 hrs.
