Question

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

Answer 1

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
