Here's the steps I took to solve:
12 miles / 1 hour = (converting hour to minutes)(1 hour = 60 minutes)
12 miles / 60 minutes = (converting miles to feet)(1 mile = 5280 feet)
63360 feet / 60 minutes = (converting feet to inches)(1 foot = 12 inches)
760320 inches / 60 minutes = (divide by 60 to make denominator 1 minute)
12672 inches / 1 minute
There are 60 minutes per hour. So there are 60 times as many inches per hour as there are inches per minute.
Bicycle wheels with a diameter of 26 inches, travelling 35 miles per hour, are turning 452 revolutions per minute. 35 miles per hour is 36,960 inches per minute (25 *5280 * 12 / 60) 26 inches diameter is 81.7 inches circumference, so the revolutions per minute is 36,960 / 81.7 or 452 revolutions per minute.
You are traveling at 6.14 miles per hour.
At 10 mph you are traveling 880 feet per minute.
You can go 0.8 miles in one minute if you are traveling at an average speed of 70 miles per hour.

5,280 inches per minute is five miles per hour.
12 mph equates to 352 yards per minute.
To solve, you need how far is travelled in 1 minute and the circumference of the wheel (in the same units) which gives how far the wheel travels in one revolution; then dividing the former by the latter will give the revolutions per minute: I'll work in inches: There are 63360 inches in 1 mile and 60 minutes in 1 hour, thus: 10mph = 10 x 63360 ÷ 60 inches per minute = 10560 ipm circumference = π x diameter = 26π inches ⇒ revolutions per minute = 10560 ipm ÷ 26π ins ~= 129.3 rpm
36 inches in three hours equates to a speed of 0.000189394 mph
For obvious reasons, let us use ipm to represent a velocity in inches per minute, and iph to represent that same velocity in inches per hour. So something is moving at the rate of ipm inches per minute. There are 60 minutes in an hour, and in every one of those minutes, it covers a distance of ipm inches. Therefore in the whole hour, altogether, it goes 60 times as far, that is, 60 ipm. That's how many inches it moves in one hour, so iph = 60 ipm Solving for ipm, the formula is: ipm = iph/60
