Zhiyuan and his family are planning to attend a football game. The time it takes Zhiyuan to get to the football stadium is dependent upon the traffic. If traffic is heavy, he will only average 30 mi/h and he
will arrive right on time. If traffic is light, he will average 55 mi/h and arrive 1 hour and 15 minutes
early. In miles, what is the distance from Zhiyuan’s house to the football stadium? Express your
answer as a decimal to the nearest tenth.
