You are riding your bicycle. It takes you 28 min to go 8 mi. If you continue traveling at the same rate, how long will it take you to go 15 mi?
+23245 You can set up a proportion: time / distance = time / distance
28 min / 8 mi = x / 15 mi
Cross multiply:
8 · x = 28 · 15 ---> 8x = 420 ---> x =
To estimate the correctness of your answer since 15 min is a little less than twice 8 min, your answer should be a little less than twice 2 min.
