A bicycle is classified by the diameter of its tires. For example, a 20-inch bicycle has tires that are 20 inches in diameter. The number of times a bicycle tire rotates in a given period of time is directly related to the distance traveled in that period of time. A 26-inch bicycle is pedaled so that the tires rotate at a rate of 200 revolutions per minute. A 20-inch bicycle is pedaled so that its tires rotate at a rate of 200 revolutions per minute, as well. How many complete rotations does either bike complete in one second? Answer in a complete sentence.
Hi double mnk,
Both tires are rotating at the same rotational speed.
200 revolutions per minute
that is :
200 revolutions EVERY minute.
There are 60 seconds in a minute so in a second the bike would have to travel a lot less distance ... so DIVIDE (by 60 of course)
How many revolutions would it be in a second then?
Can you tell me now? They want an exact answer, don't round it off.
You could be smart and say the bike does not rotate at all. only the wheels rotate. LOL
That would be 10/3 revolutions.
They ask for complete revolutions in the question so my main question is if there are 3 complete revolutions or 10/3 complete revolutions?
