Answer:
93 miles/hr
Explanation:
Speed has a unit of distance/time. We are given hours and miles, so lets look for an answer with units of miles/hour.
We know the miles (372 miles). We can find the hours by subtracting 8 (8:00AM) from 12 (noon: 12:00), The train was travelling for 4 hours.
(372 miles)/(4 hours) = 93 miles/hr
