The flathead rail tunnel in Montana is about 7 3/4 miles long. A train travels at a speed of 3/4 mile per mile minute.how long will it take for the train to go through the tunnel
7 3/4 × 3/4 = So u add 3×3=9 Then add 4×4=16 Give you 9/16 Then you add that 7 you left out with 9/16 But just the 9 not the 16 7 × 9 = 63 And your answer is 63/16 Hope i help :-)
