Answer:
3:02pm
Explanation:
we can first do 450/56 to find out how long it takes the train to travel 450 miles
this equals 8.0357142857
so this is 8 hours plus a little more time
we now have to convert that decimal into a number of minutes
60(0.0357142857)
that equals 2.142857142
so that's 2 minutes and 14 seconds
so we just need to add 8 hours 2 minutes and 14 seconds to 7:00am
which would be 3:02:14pm
