Answer: 54 miles in 1hr 30min
Explanation:
The train travels at a constant speed of 36 miles per hour. To find out how far it can travel in 1 hour 30 minutes, we need to convert the time to hours. Since there are 60 minutes in 1 hour, 1 hour 30 minutes is equal to 1.5 hours (1 hour + 30 minutes/60 minutes). To calculate the distance traveled, we multiply the speed of the train (36 miles per hour) by the time it travels (1.5 hours). So, the train can travel 36 miles per hour * 1.5 hours = 54 miles in 1 hour 30 minutes. Therefore, the train can travel a distance of 54 miles in 1 hour 30 minutes
