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.

Answer 1

52,700J x 1s/756J x 41m/1s

Step-by-step explanation:

Answer 2

total disance covered by car=2858.11 meters

Step-by-step explanation:

First calculate the time for which the given energy can be used

total energy=52700 joules;

756 joules used in every second;

`Total time=(52700joules)/(756joules/sec)`

total time=69.71 sec;

speed of car=41 m/s;

Number of meters the car travels=
`totaltime* speed of the car`

number of meters the car travels=
`69.71 * 41`

number of meers the car travel=2858.11 meters
