A car is traveling at a rate of
54
miles per hour. What is the car's rate in feet per second? How many feet will the car travel in
20
seconds? In your computations, use the fact that
1
mile is equal to
5280
feet.
To convert Daniel's rate from meters per minute to feet per hour, we will need to perform a series of unit conversions.
First, we know that there are 3.28084 feet in a meter, so we can convert Daniel's rate from meters per minute to feet per minute by multiplying his rate (2 meters/minute) by the conversion factor (3.28084 feet/meter):
2 meters/minute * 3.28084 feet/meter = 6.56168 feet/minute
Next, we need to convert Daniel's rate from feet per minute to feet per hour. To do this, we know that there are 60 minutes in an hour, so we can multiply his rate (6.56168 feet/minute) by the conversion factor (60 minutes/hour):
6.56168 feet/minute * 60 minutes/hour = 393.701 feet/hour
So, Daniel's rate is about 393.7 feet per hour. Rounding it to the nearest whole number, the answer is option D, about 394 feet per hour.
