Candace leaves her house and starts jogging at a pace of 480 feet per minute. Five minutes later, her brother runs after her at a pace of 660 feet per minute. If both of them continue at these speeds, how long will it take her brother to catch up? Here is the equation that models the problem, where t represents time in hours.
