Joey is riding a bicycle. It takes him 28 minutes to go 8 miles.
If he continues traveling at the same rate, how long will it take him to go 15 miles?
:
Distance varies directly with time, use a ratio equation to do this
let t = time to go 15 mi
t%2F28 = 15%2F8
Cross multiply
8t = 28 * 15
8t = 420
t = 420/8
t = 52.5 min to go 15 mi
