YOu first find the circumference which is C=d x pi(22/7)
C= 70(22/7)
C=220
Take 22 km and turn it into cm. SO, 21 x 100,000= 2,200,000 cm
2,200,000/ 220= 10,000 revolutions

The distance from Arcata to Crescent City is 86 miles A car was driven this distance using tires with a radius of 16 inches Approximately how many revolutions of each tire occurred on the trip?
Useful information: 86 miles tire radius of 16 inches In order to find how many revolutions the tire undertakes you must divide the amount traveld by the circumference of the tire (The length of tire tread). To find the circumference you multiply the diameter by Pi (3.14) The diameter is twice the radius or 32 inches 32 in. x 3.14 = 100.48 in. 86 miles equals 5,448,960 inches 5448960 in. /100.48 in. = 54229.3 revolutions

How fast does a truck move in meters per second if it has tires with a circumference of 2.5 meters rotating at 2 revolutions per second?
Each revolution rolls the truck ahead 1 tire-circumference.(2 revs per second) x (2.5 meters per rev) = 5 meters per second
How many miles per hour with second gear?
There are a lot of factors that go into determining this. What is the effective gear ratio for second gear? What is the maximum RPM of the engine? What is the rolling diameter of the tires? If you can provide the answers to those three questions, I can tell you the maximum speed.

How many revolutions does a tire make in a mile?
That would depend upon the size of the tire. My car has tires that are about 221/4" in diameter which means they have circumference: circumference = π x diameter ≈69.9" which is the distance travelled in one complete revolution of the tire. 1 mile = 63360 in ⇒ revolutions = 1 mile ÷ circumference_of_tire ≈ 63360 in ÷ 69.9 in ≈ 906.43 revolutions per mile My bicycle has tires that are about 271/2" in diameter meaning the number of revolutions is: revolutions ≈ 63360 in ÷ (π x 271/2 in) ≈ 733.39 revolutions per mile

Can you put 195 65R tires on a rim that now has 195 55R Tires?
Yes you can as long as the rim diameter is the same. You left off the last number on your size. The sidewall will be taller on the 65 versus the 55 and this will affect the overall diameter of the tire so your speedometer may/will be off depending on the year of your car. The 65 will make less revolutions per mile than the 55.
