The answer is: C) 3 hours and 12 min
Find the miles per hour the train is going, 75 mph. Then divide 240 by the miles per hour, and you get minutes. Convert minutes into hours
Divide 100 miles by 80 minutes, then multiply by 60 to get how many miles per hour instead of miles per minute
Then divide 240 by 75 and multiply again by 60 to get hours instead of minutes
Hope I helped!
Good Luck!
Have a great day!
