Lynette drove 248 miles in four hours at that rate how many hours will it take her to drive an additional 93 miles

Remark

The question becomes "How long does it take her to drive 248 + 93 = 341 miles?"

Answer

Set up a simple proportion.

248/4 = 341/x Cross multiply

248 * x = 4 * 341

248 x = 1364 Divide by 248

x = 1364/248

x = 5.5 hours

But you are only asked about the 93 miles.

Answer: The number of hours for 93 miles is 5.5 - 4 = 1.5
