Keith left his house, rode his bike 3 miles along one road, took a 90 degree turn, and rode 3 miles to the local swimming pool. If he had ridden directly to the pool, how much distance would he have saved? Round the answer to the nearest tenth of a mile.

A right triangle. The distance from the angle with measure 90 degrees to Keith's pool is 3 miles, and the distance to the pool is 3 miles.

Keith travelled 4.2 miles if he had ridden directly to the pool

Step-by-step explanation:

Given: In a right triangle, the distance from the angle with measure 90 degrees to Keith's pool is 3 miles, and the distance to the pool is 3 miles.

To find: Distance travelled by Keith if he moved directly from house to swimming pool

Solution:

ΔABC is a right angled triangle.

Using Pythagoras theorem, square of hypotenuse is equal to sum of squares of base and perpendicular

Keith travelled 4.2 miles if he had ridden directly to the pool

answer: c i think

step-by-step explanation:

yes. we do proportions in probabilities.
