Question

As Jupiter revolves around the sun, it travels at a speed of approximately 8 miles per second. Convert this speed to miles per minute. At this speed, how many miles will Jupiter travel in 4 minutes? Do not round your answers.

Answer 1

First to convert it you need to multiply 8 miles per second by 60 seconds because there are 60 seconds in a minute:

 8 miles    x    60 s 
1 second        1 min

The unit of seconds will cancel out so you will get 480 miles/ min

To get how far it travels in 4 min you need to multiply the speed by 4 minutes

480 miles   x  4 min
   1 min

The unit of minutes will cancel out to get 1920 miles

Therefore, jupiter travels at 480 miles per minute and in 4 minutes, it will travel 1920 miles.
