Erik drives 19.2 miles in 16 minutes. He passes a sign which gives the speed limit as 65 mph.
By how much, in mph, did Erik's average speed exceed the speed limit?​

Erik's average speed exceeds the speed limit by 6.91 miles per hour.

Step-by-step explanation:

Let suppose that Erik travels at constant speed. Hence, the speed (), measured in miles per hour, is determined by following equation of motion:

(1)

Where:

- Distance, measured in miles.

- Time, measured in hours.

Please notice that a hour equals 60 minutes. If we know that and , then the speed of Erik is:

Which is 6.91 miles per hour above the speed limit.

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
