How many miles mph does the chunnel trains go if then 69miles in 35 minutes?

To calculate the speed of the Chunnel trains in miles per hour (mph), we can use the formula:

Speed = Distance / Time

Given that the trains cover a distance of 69 miles in 35 minutes, we need to convert the time to hours. There are 60 minutes in 1 hour, so:

Time = 35 minutes = 35 / 60 = 0.583 hours

Now, we can calculate the speed:

Speed = 69 miles / 0.583 hours ≈ 118.36 mph

Therefore, the Chunnel trains travel at approximately 118.36 miles per hour.
