During a morning commute, a passenger train maintains a constant speed of $48\text{ miles per hour}$ between two city stations. If the non-stop journey takes exactly $15$ minutes, what is the total distance between the two stations?

$12\text{ miles}$ Cevap
B
$7.2\text{ miles}$
C
$120\text{ miles}$
D
$720\text{ miles}$

Cevap

The distance between the two stations is

12\text{ miles}

The correct answer is found by first converting

15

minutes to hours by dividing by

60

, which gives

0.25

hours. Then, multiplying the speed of

48\text{ miles per hour}

0.25

hours results in a distance of

12\text{ miles}

Adım Adım Çözüm

Identify the formula for distance.

Distance = Rate \times Time

This formula connects speed, time, and distance to find the unknown value.

Convert the travel time from minutes to hours.

15 \text{ minutes} = \frac{15}{60} \text{ hours} = 0.25 \text{ hours}

The rate is given in miles per hour, so the time must be in hours to cancel out the units correctly.

Multiply the rate by the converted time.

48 \times 0.25 = 12

Applying the values to the distance formula yields the total distance in miles.
