10 minutes 20 seconds

Step-by-step explanation:

It is given that the flat head rail tunnel in Montana is about $7\frac{3}{4}$ miles long.

Length of rail tunnel = $7\frac{3}{4}=\frac{28+3}{4}=\frac{31}{4}$

A train travels at a speed of 3/4 miles per minute.

$Speed=\frac{3}{4}$ miles

The formula for time is

$Time=\frac{Distance}{Speed}$

$Time=\frac{\frac{31}{4}}{\frac{3}{4}}$

$Time=\frac{31}{3}$

$Time=10\frac{1}{3}$

$(10\frac{1}{3})\text{ minutes}=10 \text{ minutes}+\frac{1}{3}\text{ minutes}=10 \text{ minutes}+20\text{ seconds}$

Therefore, the time taken by the train to go through the tunnel is 10 minutes 20 seconds.
