Answer:
A jet airplane travels at an average speed of 1,200 miles per hour. To calculate how many miles it travels in one minute, we need to convert the speed from hours to minutes.
There are 60 minutes in an hour, so we can divide the speed of 1,200 miles per hour by 60 to find the speed in miles per minute.
1,200 miles per hour / 60 minutes = 20 miles per minute.
Therefore, a jet airplane traveling at an average speed of 1,200 miles per hour would travel approximately 20 miles in one minute.
