well, first you have to find the original circumference. this is 125 times Pi. once you have this number (392.6), then you have the measure of one revolution. because you need the distance if someone went around it 5 times, you simply multiply it by five, and your result is 1963.4 ft. but you really should try to do your homework by yourself, rather than ask people online.
The distance travelled by the person on the Ferris wheel is 1962.5 feet. To find the distance travelled you will first find the circumference using the formula Pi (3.14) times diameter (125 ft) and then multiply by five.
