During a surveillance operation, a drone flies steadily at a rate of $90 \text{ miles per hour}$ . Given that $1 \text{ mile} = 5,280 \text{ feet}$ , how many feet does the drone cover every second?

Cevap: 132 / 132 feet / 132 ft / 132 feet per second / 132 ft/s / 132 fps / 132 ft/sec

Cevap

132

The drone's speed is

90 \text{ miles per hour}

. First, convert the distance from miles to feet:

90 \text{ miles} \times 5,280 \text{ feet/mile} = 475,200 \text{ feet}

. This is the distance traveled in one hour. Because there are

60 \text{ minutes}

in an hour and

60 \text{ seconds}

in a minute, one hour equals

3,600 \text{ seconds}

. To find the distance traveled in one second, divide the total feet by the total seconds:

475,200 \div 3,600 = 132 \text{ feet}

Adım Adım Çözüm

Determine the distance the drone travels in one hour in feet.

90 \times 5,280 = 475,200 \text{ feet per hour}

Since there are

5,280 \text{ feet}

in one mile, multiplying the speed in miles per hour by

5,280

converts the distance unit from miles to feet.

Determine the number of seconds in one hour.

60 \times 60 = 3,600 \text{ seconds}

There are

60 \text{ minutes}

in an hour and

60 \text{ seconds}

in a minute.

Calculate the distance covered in one second.

475,200 \div 3,600 = 132 \text{ feet per second}

Dividing the total distance covered in one hour by the total number of seconds in one hour gives the speed in feet per second.

Anahtar Kavram

To convert a rate from miles per hour to feet per second, multiply the distance by

5,280

(feet per mile) and divide the time by

3,600

(seconds per hour).
