First, we need to calculate the circumference of the bicycle wheel using its diameter:
Circumference = π x Diameter
Circumference = 3.14 x 2.8 ft
Circumference = 8.792 ft
Next, we need to find the distance traveled by the bicycle wheel in 2 hours, given that it rotates at 40 revolutions per minute:
1 revolution = circumference
40 revolutions = 40 x circumference
40 revolutions = 40 x 8.792 ft
40 revolutions = 351.68 ft
So, the distance traveled by the bicycle wheel in 1 minute is 351.68 ft.
To find the distance traveled in 2 hours, we need to convert 2 hours to minutes:
2 hours = 2 x 60 minutes = 120 minutes
Finally, we can calculate the total distance traveled in 2 hours:
Distance traveled = 351.68 ft/minute x 120 minutes
Distance traveled = 42,201.6 ft
Therefore, the bicycle wheel will travel a distance of 42,201.6 ft in 2 hours.
