Question

If an airplane speed is 300 miles per hour what is the speed in feet per second

1 mile = 5280 feet
1minute = 60 seconds
1 hour = 60 minutes

Answer 1

To convert the speed of an airplane from miles per hour to feet per second, we need to consider the conversion factors.

Given:

- Airplane speed = 300 miles per hour Conversion factor: 1 mile = 5280 feet

Conversion factor: 1 hour = 60 minutes

Conversion factor: 1 minute = 60 seconds

First, let's convert miles to feet: 300 miles/hour * 5280 feet/mile = 1,584,000 feet/hour

Next, let's convert hours to seconds: - 1 hour = 60 minutes * 60 seconds = 3600 seconds

Finally, let's convert feet per hour to feet per second:

1,584,000 feet/hour / 3600 seconds/ hour = 440 feet/second

Therefore, the speed of the airplane in feet per second is approximately 440 feet/ second.

Answer 2

To convert 300 miles per hour to feet per second, multiply by 5280 feet per mile, and then divide by 3600 seconds per hour, which equals 440 feet per second.

Step-by-step explanation:

To convert the speed of an airplane from miles per hour to feet per second, we need to take into account the conversion factors given. One mile is equal to 5280 feet, one hour is equal to 60 minutes, and one minute is equal to 60 seconds. Therefore, to convert 300 miles per hour to feet per second, we can use the following conversion: 300 miles/hour x 5280 feet/1 mile x 1 hour/60 minutes x 1 minute/60 seconds = 440 feet/second. So, the speed of the airplane is 440 feet per second.
