Hi there! To start with this situation, you are going to want to first divide 245 and 5 so you can find out how many miles this woman drives in 1 hour. We do that and get 49. Now is the easy part. Multiply 49 and 7. She will drive 343 miles in 7 hours.
Sum and difference problem.
Longer carrier = (sum+difference)/2 = (4198+10)/2 = 2104 ft
Shorter carrier = (sum-difference)/2 = (4198-10)/2 = 2094 ft.
