(60 × 4) + 45 = 285 minutes Method: There are 60 minutes in 1 hour: 60 minutes x 4 hours equals 240 minutes. There are 45 minutes in 3 quarters of 1 hour. Therefore, add 240 and 45 which equals 285 minutes.
108/45 = x/100 > 45x = 10800 > x = 240
In 3 hours, there are 10,800 seconds (3 hours x 60 minutes x 60 seconds). If the Ferris wheel takes 45 seconds for a complete rotation, it will complete 240 rotations in 3 hours (10,800 seconds / 45 seconds per rotation).
There are 35 240 in 8400
240 ÷ 16 = 15
240 ÷ 2 = 120
There are 240/2 = 120 of them
