If two planes leave the same airport at 1:00 PM, how many miles apart will they be a 00 PM if one travels directly north at 150 mph and the other travels directly west at 200 mph?
সমাধান
সঠিক উত্তর: Option C
since one plane travel north, the other west, they are at right angles
North = 150X2 =300
West = 200X2=400
By Pythagoras' Theorem, 300 square + 400 square = x square( where x is the distance) x = 500m
