1000 meters are 1km so 700 meters
To answer this item, we let x be the time for the faster plane and h be the distance traveled which is the same for both planes. Distance is calculated by multiplying speed and time. Thus,
(558)(x) = (496)(x + 0.5)
The value of x from the equation is 4.
I am not sure but I think it is B 21 units
