Davit drives 16.5 miles in 10 minutes.
He passes a sign which gives the speed limit as 65 mph.
By how much, in mph, did Davit's average speed exceed the speed limit?

Answer 1

Answer:

34 mph

Step-by-step explanation:

Davit's average speed in miles per minute

= 16.5/10

= 1.65 miles per minute

Davit's average speed in miles per hour

= 1.65 × 60 (Since there are 60 minutes in 1 hour)

= 99 mph

Difference = 99 - 65

= 34 mph
