The answer to this question is 2. If an airplane takes off from a location at 17 S latitude and flies to a new location 55 due north of its starting point, then the plane will have successfully reached a latitude of 38 degrees north. This can be answered with a little bit of math and some critical thinking. Keep in mind that the equator is 0 degrees, so the airplane has crossed it on the journey to the new location.
Since the plane started at 17 S, you could treat it as a number line which means that 17S is also -17 degrees. If the airplane continued north for 55 degrees, then you could subtract that -17 from 55 and you will arrive at the correct answer of 38 degrees north.
The correct answer to the question “What latitude has the plane reached” if “an airplane takes off from a location at 17 S latitude and flies to a new location 55 due north of its starting point” is 38 degrees north (2). The answer is fairly simple to explain. We all know that the equator is 0 degrees, and we should take that into account if the airplane has crossed the equator.
Now, we should assign the latitude south as a negative value. In this scenario, we can assume that the airplane started at -17 degrees. So, if the airplane flew 55 degrees north, then it would just mean that the latitude is 55 degrees minus 17 degrees. Using that formula, we will get the answer: 38 degrees North.
