First off, 1,000 meters is equal to 1 kilometer, so 3,000 meters is equal to 3 kilometers. Secondly, 1 foot is just 12 inches, so 5 feet is just 12 multiplied by 5, which is 60. Now, because it is 5 feet 6 inches we add the 6 inches to our 5 feet that we just coverted to inches, which is 60+6=66. Quick rundown, the first question is 3 kilometers, and the second one is 66 inches.
