A surveillance drone flies at a constant speed of $40$ miles per hour. How many minutes will it take the drone to travel a distance of $10$ miles?

15

minutes

The correct answer is found by dividing the distance (

10

miles) by the speed (

40

miles per hour) to get the time in hours, which is

0.25

hours. Then, converting hours to minutes by multiplying by

60

gives exactly

15

minutes.

Calculate the time required in hours.

0.25

hours

Time is equal to distance divided by rate. Dividing

10

miles by

40

miles per hour gives

0.25

hours.

Convert the time from hours into minutes.

15

minutes

Since there are

60

minutes in an hour, multiplying

0.25

hours by

60

yields

15

minutes.

Calculating elapsed time using the distance formula and converting units of time.
