PLEASE HELP! I WILL DO BRAINLIST! The athlete jogged a distance of 4850 yards in 20 minutes. What is the time needed to cover 9215 yards at the same rate?

Let x be the time needed to cover 9215 yards.

Equation :

Answer :

Equation: 20 / 4850 = x / 9215   37.99 minutes

Step-by-step explanation:

I don't know what kind of equation you need but the equation I wrote is the one I used to solve this. You must divide the amount of time it took to run the distance which is 20 minutes by the yards jogged which is 4850. That will give you the amount of time it took the athlete to jog one yard which you should then multiply by 9215 yards to find out how much time would be needed to cover that distance. In the equation, if you replace the "x" with the answer (37.99), the equations should be equal.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
