Answer:
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.
Hi!
A <u>hypotenuse</u> is the longest leg in a right triangle.
A <u>right triangle</u> is a triangle that has one 90 degree angle.
The hypotenuse is always directly across from the right angle.
In pictures, right angles are represented by a square.
<u><em>Therefore, the side with the hypotenuse is side 3</em></u>, because we can see that the angle between side 1 and side 2 is the right angle, and the hypotenuse would be directly across.
