15 minutes is one quarter of an hour, so the number of people accommodated in an hour would be 4 x 55 = 220 people per hour.
Then, multiply the number of people per hour by the 6 hours:
6 hours x 220 people =1320 people in 6 hours.
55 per 15 x4 60x 6= 6 hours
55 times 4 times 6 and 1,320 rode on it
