Edmonton is 220 kilometers north of Red Deer. Calgary is 110 kilometers south of Red Deer. If you travel at 110 kilometers per hour, how long will it take to get from Edmonton to Calgary? Give me reasons, before answering the question
Total distance travelled is 220km + 110km = 330 km. Time to travel that far is 330km / 110km / hour = 3 hours. So the final answer is 3.
