A tire of a moving bicycle has radius 16 in. If the tire is making 2 rotations per second, find the bicycle’s speed in miles per hour.

Answer:

the bike is going 32 inches per second since the wheel is making 2 rotations per second and the size of it is 16 inches, there are 63,360 inches in a mile and there are 60 seconds per minute. multiply 32 by 60 to get inches per minute then multiply that number by 60 to get inches per hour now we have 115,200 inches per hour, and idk how to do the rest but that should help
