it covers 300 miles in the first hour, 315 miles the second hour, 330 miles in the 3 hour.
683 miles - 615 = 68 miles to be covered at 330 miles per hour. 1 divided by 330/68 = 0.206 x 60 (mins) = 12.36 minutes
So 2 hours and 12.36 minutes.
Unless it's a silly trick question. eg: does it need to slow down? Is there a train that even goes there, etc.
Simple grade 1 math.
