a car went 44 feet through an intersection in only 0.5 seconds. How fast was the car going in miles per hour?
44Ft/0.5s * 1mi/5280Ft * 3600s/h = 60 mi/h.
Memorize this conversion factor:
60mph=88f/s
60mph/88fps *(44/.5)fps=60mph
To find the speed of the car in miles per hour, we need to convert the distance traveled and the time taken into the appropriate units.
1 mile = 5280 feet (approximately)
1 hour = 3600 seconds
Step 1: Convert the distance traveled from feet to miles.
44 feet * (1 mile / 5280 feet) = 0.00833 miles
Step 2: Convert the time taken from seconds to hours.
0.5 seconds * (1 hour / 3600 seconds) = 0.000139 hours
Step 3: Calculate the speed of the car by dividing the distance by the time.
Speed = Distance / Time
Speed = 0.00833 miles / 0.000139 hours = 59.964 miles per hour
Therefore, the car was going approximately 59.964 miles per hour.
To determine the speed of the car in miles per hour, we need to convert the distance traveled and the time taken to the appropriate units.
1. Convert feet to miles:
There are 5280 feet in a mile, so we divide the distance in feet by 5280.
44 feet ÷ 5280 = 0.0083 miles
2. Convert seconds to hours:
There are 60 seconds in a minute and 60 minutes in an hour, so we divide the time in seconds by 3600.
0.5 seconds ÷ 3600 = 0.000139 hours
3. Calculate the speed in miles per hour:
Speed = Distance ÷ Time
Speed = 0.0083 miles ÷ 0.000139 hours
Speed ≈ 59.71 miles per hour
Therefore, the car was traveling at approximately 59.71 miles per hour.
