Let’s come back to the equation of SPEED OF AN ECHO
SPEED =2XDISTANCE/ TIME
So 337*7/2=1179.5 nearest meter =1800 m away
Hope you will get it right
If an object is moving, then its speed and the magnitude
of its velocity aren't zero.
If its velocity is constant (speed doesn't change and it's
moving in a straight line), then its acceleration is zero.
Looks like choice-D sums it up nicely.
