What is the unit rate for 822.6 km in 18 h? enter your answer, as a decimal, in the box.

we know that

A unit rate is a ratio between two different units with a denominator of one

In this problem to find the unit rate divide the total distance by the total time

so

therefore

the answer is

The unit rate is equal to

By drawing a diagonal in a square you are dividing the square into two congruent isosceles right triangles. Using Pythagorean Theorem we can find the length of the diagonal.

a squared + b squared = c squared
a and b represent the sides of the triangle (aka the length of a side of the square), and c represents the hypotenuse (aka the diagonal).
9 squared + 9 squared = c squared
81 + 81 = c squared
162 = c squared
take the square root of both sides
81= x
