Kimberly traveled to her friend's house and went 300miles in 5 hour. On her way home she took a different route and trveled 420 miles in 7 hours. Are these ratios equivalent? Use proportion to show complete work.

300 miles/5 hours=60 miles per hour420 miles/7 hours=60 miles per hour therefore they both have an equivalent proportion of 60 miles per hour

Here the average speed for going to friends house = 300/5 miles/hr= 60 miles/hour And average speed while coming back = 420/7 miles/hour =60 miles/hourI.e. 300/5 = 420/7 = 60 miles/hr Hence the ratios are equivalent in both ways
