d. 211,200 ft/min

Answer 1

To convert 40 miles per hour to feet per minute, multiply 40 by 5280 to convert miles to feet, then divide by 60 to convert hours to minutes, resulting in 3,520 feet per minute.

Step-by-step explanation:

The student has asked how to convert a car's speed of 40 miles per hour to feet per minute. To do this conversion, we need to know there are 5280 feet in a mile and 60 minutes in an hour. We can use these conversions:

1. First, convert miles to feet: 40 miles × 5280 feet/mile = 211,200 feet.
2. Then, convert hours to minutes: 211,200 feet ÷ 60 minutes/hour = 3,520 feet/minute.

Therefore, a car traveling at a speed of 40 miles per hour is moving at 3,520 feet per minute.
