Given :
Distance travelled by plane 1 in an hour = 300 miles
Distance travelled by plane 2 in an hour = 600 miles
So, distance travelled by them together in an hour = (300 + 600) miles
Now, according to question planes are traveling in opposite direction.
Here, speed = 900 miles/hour
Distance = 2700 miles
Time = ?
We know, Time = distance/speed
= 2700/900
= 3 hours
Thus, planes will be 2700 miles apart in 3 hours
