Convert the target speed to feet/sec.
40mi%2Fhr*1%2F3600hr%2Fs*5280ft%2Fmi=58.7f%2Fs
.
.
.
Convert the distance between them to feet.
40yds3feet%2Fyd=120ft
.
.
.
So the object is moving relative to the target at a speed of
700-58.7=641.3f%2Fs
So then the time for the object to travel 120 feet is,
t=120%2F641.3=0.19s
