Question

question a car travels at a speed of 41 meters/second using 756 joules of energy every second. suppose we know that the car uses 52,700 joules of energy. set up a calculation to find the number of meters the car travels with this amount of energy. drag each tile to the correct location. the tiles can be used more than once. 52,700 j x x 756 41 s 1 m

Explanation:

Step1: Set up proportion

Let $x$ be the number of meters. We know that the car uses 756 joules per meter and has a total of 52700 joules. The proportion is $\frac{756\text{ J}}{1\text{ m}}=\frac{52700\text{ J}}{x\text{ m}}$.

Step2: Cross - multiply

$756x = 52700$.

Step3: Solve for $x$

$x=\frac{52700}{756}$.

Answer:

$x=\frac{52700}{756}$
