An airplane flies 105 miles in ½ hour. How far can it fly in 1 ¼ hours at the same rate of speed?
Well, if we’re talking, here, a constant rate of travel, and not factoring in the various factors that can affect a plane’s progress (e.g. flying into a headwind, or with a tailwind, or a crosswind, or changing altitudes, to different air densities, and other factors. None are specified in the original question, only the fact that the plane is covering 105 miles in 1/2 hour.) then, travelling 105 miles in a half hour implies that it will be travelling at 210 mph. Therefore the plane, maintaing this rate of travel for an hour and a quarter will travel 210 x 1.25 miles, which works out to 262.5 miles. Now, if only the real world was this calm and didn’t constantly throw surprises at us.
