The expression that gives the train's speed in miles per hour is:
Speed = 524 / 4.5 = 116.44 miles per hour.
To find the train's speed in miles per hour, you can use the formula:
Speed (in miles per hour) = Distance (in miles) / Time (in hours)
In this case, the distance the train travels is 524 miles, and the time it takes is 4 1/2 hours. To convert 4 1/2 hours into a decimal, you can calculate it as follows:
4 1/2 hours = 4 + 1/2 = 4.5 hours
Now, you can use the formula to calculate the speed:
Speed (in miles per hour) = 524 miles / 4.5 hours
Speed (in miles per hour) = 116.44 miles per hour (rounded to two decimal places)
So, the expression that gives the train's speed in miles per hour is:
Speed = 524 / 4.5 = 116.44 miles per hour
