Question

A car travels 25 miles every half-hour. How fast is it going?

Answer 1

Answer:

The car is going 50 miles an hour.

Step-by-step explanation:

Since the car is going 25 miles every half-hour, it is going 50 miles an hour

That is because there are two half hours in an hour

25*2 = 50

The car is going 50 MPH

Answer 2

The speed of the car is 50 miles/hour.

Speed, distance, and Time

We know that sped, distance, and time all are in a relationship to each other. this relationship can be given as,

$\rm{Speed = \dfrac{Distance}{Time}$

Given to us

1. Distance traveled by car = 25 miles,
2. Time taken by car = half-hour = $\dfrac{1}{2}$ = 0.5 hour

Speed of the car

We know that to measure how fast is something is traveling we measure the speed of the object.

$\rm{ Speed\ of\ the\ car=\dfrac{Distance\ travelled\ by\ car}{Time\ taken\ by\ car}$

                          $=\dfrac{25\ miles}{0.5\ hour}\\\\ =50\ miles/hour$

Hence, the speed of the car is 50 miles/hour.
