An instrument shows the number of revolutions per
minute made by each tire of a car. In each revolution, the
car travels a distance equal to the circumference of one of
its tires. The circumference of each tire is equal to 2πr,
where r is the radius of the tire.
If the radius of each tire on Maria’s car is 0.30 meter,
what is the approximate speed of Maria’s car, to the
nearest kilometer per hour, when the instrument is
showing 779 revolutions per minute?
(1 kilometer = 1000 meters)

Dana rode her bicycle 600 miles one summer before she had to replace the tire on her front wheel. The diameter of the front wheel is 24 inches. What is the best estimate of the number of revolutions made by the tire before it had
Would someone like to help me with these questions? Steps appreciated~ 1. If the diameter of a monster truck tire is 3.5 m and it makes one rotation every 5 seconds, how far does the tire roll in 1 minute?
The diameter of a car tire is approximately 0.6meters. The warranty is good for 70,000 km. About how many revolutions will the tire make before the warranty is up? More than a million? a billion? ----------------------- my work
y= X^2 + X - 500/10 and y is the number of milliliters of fuel consumed per second and X is the speed of the engine in revolutions per minute. If the engine operates between 100 revolutions per minute and 400 revolutions per
