An airplane flies with a constant speed of 540 miles per hour. How far can it travel in 1 1/4 hours?

Hey!

Your answer is 675 MILES!

Explanation:

Using the S = D x T formula...

We first need to convert any values... 1 1/4 hours--75 mins (1.25hrs)

So now we substitute into the formula!

D (distance)= 540 x 1.25 = 675     (Distance = Speed x Time)

Distance Travelled= 675 MILES!

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
