A cyclist rides his bike at a speed of
18 miles per hour. What is this speed in feet per second? How many feet will the cyclist travel in 10
seconds? In your computations, use the fact that
mile is equal to
feet. Do not round your answers.
5280 ft in a mi ... 3600 s in an hr
ft/s = 18 * 5280 / 3600
18mi/hr * 5280ft/mi * 1hr/3600s = 26.4 ft/s.
To convert miles per hour to feet per second, we need to consider the conversion factor.
1 mile = 5280 feet
1 hour = 3600 seconds
To convert 18 miles per hour to feet per second:
(18 miles/hour) * (5280 feet/mile) * (1 hour/3600 seconds)
Calculating this expression, we get:
(18 * 5280) / (3600) = 26.4 feet/second
Therefore, the cyclist's speed in feet per second is 26.4 feet/second.
To find out how many feet the cyclist will travel in 10 seconds, we can multiply the speed (26.4 feet/second) by the time (10 seconds):
Distance = Speed * Time
Distance = 26.4 feet/second * 10 seconds
Distance = 264 feet
Therefore, the cyclist will travel 264 feet in 10 seconds.
To find the speed in feet per second, we need to convert miles to feet and hours to seconds.
First, let's convert 18 miles to feet. We know that 1 mile is equal to 5280 feet. So, to convert to feet, we multiply the number of miles by 5280.
18 miles * 5280 feet/mile = 95040 feet
Now, we need to convert hours to seconds. We know that 1 hour is equal to 60 minutes and 1 minute is equal to 60 seconds. So, 1 hour is equal to 60 * 60 = 3600 seconds.
Now, let's compute the speed in feet per second:
Speed = Distance / Time
Speed = 95040 feet / 3600 seconds = 26.4 feet per second
Therefore, the speed of the cyclist is 26.4 feet per second.
To find out how many feet the cyclist will travel in 10 seconds, we can use the formula:
Distance = Speed * Time
Distance = 26.4 feet per second * 10 seconds = 264 feet
Therefore, the cyclist will travel 264 feet in 10 seconds.
