Final answer:
The bicycle will cover approximately 1056 feet in 40 seconds.
Step-by-step explanation:
To calculate the distance covered by a bicycle in 40 seconds, we need to convert its speed from miles per hour to feet per second.
To do this, we can use the conversion factor 1 mile = 5280 feet and 1 hour = 3600 seconds. So, the speed of the bicycle in feet per second is:
18 miles/hour * (5280 feet/1 mile) * (1 hour/3600 seconds) = 26.4 feet/second
Now, we can calculate the distance it will cover in 40 seconds by multiplying the speed by the time:
26.4 feet/second * 40 seconds = 1056 feet
Therefore, the bicycle will cover approximately 1056 feet in 40 seconds.
