OK, this is a standard conversion question-- meters to feet...
...with the wild and crazy tricky curveball thrown in there that she's swimming 3 laps.
Ooh. Brutal. Aquaman is apparently a very demanding instructor.
So we need to convert 150 meters into uh... how many feet?
Just rounding and assuming we don't have a calculator or an iPhone or a geeky kid handy
to do the math in his head...we can figure this one out fast.
A meter is roughly 1.1 yards -- i.e. a meter is a bit longer than a yard.
So it makes sense that the number of yards would be a bit longer...
and if it was exactly 1.1 times longer...
...we could multiple the 150 meters by 1.1 to get roughly 165 yards...
...but they want the ANSWER in feet -- so multiply that 165 by 3 and we get 495...
...which is close enough to 487 for military work.
The answer is D.
