No. Mike wrote the ratio as the amount of change to the new amount. He should have used the ratio of the amount of change to the original amount, which is 55

55/275 , or 20%.

20%
220 divided by 275 to get .8 
80% then 80% minus 100%
=20%

Desrina travels 70 miles at an average speed of 70 mph.
Marizza181 [45]

Total miles = 70 + 70 = 140 miles

Total time = 140 miles / 57 mph = 2.456 hours

Time 1: 70 miles / 70 mph = 1 hour

Time 2:  70 miles / x mph

Total time = time 1  + time 2:

2.456 = 1 hour + 70/x

Subtract 1 hour from both sides:

1.456 = 70x

multiply both sides by x:

1.456x = 70

Divide both sides by 1.456:

x = 70/1.456

x = 48.0769 miles per hour

Rounded to 2 dp = 48.08 miles per hour
