A bus traveling at an average rate of 50 kilometers per hour made the trip to town in 6 hours. If it had traveled at 45 kilometers per hour, how many more minutes would it have taken to make the trip? Let me see. D = rt D = 50(6) D = 300 kilometers 300 = 45t 300/45 = t 6.666667 = t How do I convert 6.666667 to minutes?
