Answer: The wheels turn about 3771 times in 5 miles.
Step-by-step explanation:
Given, Kelly rides on her bicycle such that the number of times wheels turn for every 140 feet = 20
Turns for every feet = ...(i)
To find : Number of times wheels turn in 5 miles.
Since , 1 mile = 5,280 feet
Then, 5 miles = 5 x (5,280 feet) = 26,400 feet
Now , Number of times the wheels turn in 26,400 feet = 26400 x (Turns for every feet)
[From (i)
Hence, the wheels turn about 3771 times in 5 miles.
The formula for the area of a triangle is:
where B is the base of the triangle and h is the height
It appears that the height of the triangle is 5 units (not quite 4.5) and the base is 10 units.
Multiply these to get 50, and divide by 2 to get 25.
The area of the triangle should be 25 u²
Hope this helps! :)
