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
