Question 1201678
<br>
"works from 8 am to 5pm to 4pm"???<br>
I can't help you find the answer if I don't know the right information.<br>
Each round trip takes 65 minutes.  Convert the amount of time the train works to minutes and divide that number by 65 to find the number of round trips.  Since the problem asks for an approximate number of round trips, round the result of that calculation to the nearest whole number.<br>
