Question: Two trains left the station at the same time, but took different tracks to their destination. One took a track that was 200 miles long and it went 50 MPH. The other took the other track that was 240 miles long and it went 80 MPH. How much time did it take them on average? (Round to the nearest integer.) Think carefully first, then make a decision:
The first train took 5 hours because 200 / 40 = 5. The second train took 3 hours because because 240 / 80 = 3. The total time was 8 hours because 5 + 3 = 8. The average time was 4 hours because 8 / 2 = 4. So the answer is 4.
