As Mercury revolves around the sun, it travels at a speed of approximately

30 miles per second. Convert this speed to miles per minute. At this speed, how many miles will Mercury travel in 5 minutes?

There are 60 seconds in one minute, so you would multiply the speed per second by 60 to get the speed per minute:

30 x 60 = 1,800 miles per minute.

Now multiply the speed per minute by the number of minutes traveled:

1,800 x 5 = 9,000 miles in 5 minutes.
