At an amusement park, 360 visitors rode the roller coaster in 3 hours. Write and solve a proportion to find the numbers of visitors at this rate who will ride the roller coaster in 7 hours

So first off you divide 360 visitors by 3 hours this will give you the average amount of visitors per hour 360/3=120 so there are about 120 visitors per hour then you would multiply 120 by 7 to find out the amount of people who would ride the coaster in 7 hours. 120 times 7=840
