In this question you have to find out what the unit rate is so what you do is 366/6=61 so that means 61 is the miles you cover in 1 hour so now multiply 61 starting by six until you get to 427 so: 61*6=366, 61*7=427
.
So it would take terry 7 hours at the same speed to reach 427 miles.
Answer: 7 hours
