Which means that the hypotenuse (longest side of a right triangle) squared is equal to the sum of its squared sides. In this case we are given the side lengths of 8 and 15 feet.

h^2=8^2+15^2

h^2=64+225

h^2=289

h=17 ft

The ladder is 17 feet long.

To find the average speed in miles per hour, you can find the number of miles Khalil traveled per minute and then multiply that by 60 to convert it to hours.

54 miles/45 minutes = 1.2 miles per minute

1.2 x 60 = 72 miles per hour.

Khalil traveled at an average speed of 72 miles per hour.
