At TopSpeed a rabbit can cover 7 miles in 12 minutes if a rabbit could continue at this rate in definitely how long would it take the rabbit to cross the 220 mile expense of Mojave desert

It will take about 6 hours and 17 minutes.

You can it like this:

(12/7) x 220

12/7 is the number of minutes it takes the rabbit to travel 1 mile, and 220 is the number of miles it will travel. If we multiply these two together, we will get the number of minutes needed for it to travel 220 miles.

The, answer is about 377 minutes.
