After the bomb is dropped it will start travelling in the direction of plane with speed 140m/s until it drops.
First, we need to find the time in which the bomb will drop on the ground.
$h=\dfrac{1}{2}gt^2\implies t=\sqrt{\dfrac{2h}{g}}=4s$
Hence the horizontal distance it will travel before hitting the ground= $v\times t=140m/s\times 4s=560m$
