Question

at a state park, every 1/10 mile of a walking trail is marked. every 1/4 mile of a separate biking trail is marked. You passed 8 walking trails markers and 9 biking trail markers. Your friend passed 12 walking trail markers and 6 biking markers. Who traveled farther? How much farther?

Answer 1

you pass 8 *1/10 + 9 * 1/4 = 8/10 + 9/4 = 16/20 + 45/20 = 61/20 = 3.05 miles

friend pass 12 * 1/10 + 6 * 1/4 = 12/10 + 6/4 = 24/20 + 30/20 = 54/20 = 2.7 miles

you walked further by 3.05 - 2.7 = 0.35 miles
