Question

an ostrich can run at a rate of 50 miles in 60 minutes. at this rate, how long would it take an ostrich to run 15 miles?

50 miles/ 60 min = 15 miles/ x 15(60) = 50x 900= 50x the answer is 18.
it will take the ostrich 18 minutes to run 15 miles.

50/60 = 15/x
50x = 900
50/900 = 18 minutes
