I'm pretty sure you mean how many *hours* to the destination and not *miles*. (Miles is obvious, it's 165. 224 - 59 = 165.)
I'll guide you through this:
224 is the miles you want to achieve. 59 is the base amount that you have already achieved. You drive 55 mph.
Assuming that the speed she drives is constant:
224 = 55x + 59, whereas x is the amount of hours.
Firstly, get 59 on the other side, so:
165 = 55x
Divide both sides by 55.
x = 3
It will take 3 more hours to drive to the destination.

Shes needs to drive 224 miles, but she already drove 59 miles so "224 - 59 = 165" She's driving 55 Miles an hour so...how many times does 55 go into 165? Figure the hours by dividing 165 / 55 = 3Hours there you go.

First findthe remaining distance.
224-59= 165 miles
Driving 55 miles per hour
165/55 to find the hours
That comes to 3 hours left to drive.
165 miles left to travel, it will 3 hours.

224 total destination
59 miles already driven
------------------------------
165 miles to drive
Driving at 55 mph would be 165/55=3 hours more to drive
