Answer:
684 Hours.
Step-by-step explanation:
If the plane travelled that distance in 5 hours, then all you need to do is divide the distance by 5 to get the distance travelled in one hour. This is obviously presuming that the speed travelled was constant or that this is an average figure.
3420/5 = 684.
X and w is 105 degrees and y and z are 86 degrees. since line L is a straight line it would have to add up to 180 and same with line M
