The formula d = rt gives the distance traveled in time t at rate r. a bicyclist rides for 1.25 hours and travels 32 miles.

what was the bicyclist's average speed?

divide distance by time

32  /1.25 = 25.6 miles per hour

a .4y4

hope this !

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
