Question

Any and her family were traveling during vacation. She looked at her watch at point 1 in the diagram below,and then again at point 2 in the diagram below. Her mom told her how far they traveled, as noted below.

Answer 1

so if in 2 hours you drove 80 miles the in 1 hour you have to have driven 40 miles (80m/2h)

so you have to divide the 1200 miles by the 40mph to find out how many hours the trip will take (1200m/40mph=30h)
