Aliza needs to run at a rate faster than 8.8 feet per second in order to exceed her fastest time in a race. after running for 15 minutes, her coach determines that she is running at an average rate of 5.8 miles per hour. he converts the average rate to feet per second as shown below:
he concludes that she is not running fast enough to exceed her fastest time

Correct: He used an incorrect time ratio converting hours to minutes.

X His units do not cancel.

X He used an incorrect distance ratio converting miles to feet.

Correct: He incorrectly concluded that she is not running fast enough.

X He cannot determine her average rate in miles per hour after only 15 minutes.

Step-by-step explanation:

take it another

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
