On a map, the length of a nature trail is 7.2 centimeters. If the scale is 1 centimeter to 25 kilometers, what is the actual length of the trail? Round to the nearest tenth when necessary. HINT: Set up and solve as a proportion and find x.
Accepted Solution
A:
1/25 = 7.2/x.....1 cm to 25 km = 7.2 cm to x km cross multiply (1)(x) = (7.2)(25) x = 180 km <===
