To convert the speed from feet per second to miles per hour, we need to use the conversion factor.
1 mile = 5280 feet
1 hour = 3600 seconds
So, to convert the speed from feet per second to miles per hour, we can follow these steps:
Step 1: Convert the speed from feet per second to feet per hour.
To convert from feet per second to feet per hour, we multiply the speed by the number of seconds in an hour.
Speed (in feet per hour) = Speed (in feet per second) × 3600
Speed (in feet per hour) = 44 feet/second × 3600
Speed (in feet per hour) = 158,400 feet/hour
Step 2: Convert the speed from feet per hour to miles per hour.
To convert from feet per hour to miles per hour, we divide the speed by the number of feet in a mile.
Speed (in miles per hour) = Speed (in feet per hour) ÷ 5280
Speed (in miles per hour) = 158,400 feet/hour ÷ 5280
Speed (in miles per hour) = 30 miles/hour
So, the speed of the car is 30 miles per hour.
