If an aircraft travels 120 miles in 12 minutes, what is its speed in miles per hour?

• A. 400 mph
• B. 500 mph
• C. 600 mph
• D. 700 mph

Answer: (C)

To determine the speed of the aircraft in miles per hour, we start with the distance it travels and the time it takes to travel that distance. The aircraft travels 120 miles in 12 minutes.

First, we need to convert the travel time from minutes to hours because speed is typically expressed in miles per hour. There are 60 minutes in 1 hour, so we convert 12 minutes to hours:

[

12 \text{ minutes} = \frac{12}{60} \text{ hours} = 0.2 \text{ hours}

]

Next, we can calculate the speed using the formula for speed, which is:

[

\text{Speed} = \frac{\text{Distance}}{\text{Time}}

]

Substituting the known values into the formula gives us:

[

\text{Speed} = \frac{120 \text{ miles}}{0.2 \text{ hours}}

]

Carrying out the division:

[

\text{Speed} = 120 \div 0.2 = 120 \times 5 = 600 \text{ mph}

]

This result shows that the aircraft's speed is 600 miles per hour, confirming that the
