recall d = rt, distance = rate * time.
let's say airplane A is going at a rate of "r", therefore airplane B is moving faster, at a rate of "r + 80".
now, after 3 hours, both planes have been travelling for 3 hours each, and say if A has covered "d" miles, then B has covered the slack of 2490 - d.
Answer:
12.41 minutes.
Step-by-step explanation:
It is given in the question that a plane can fly 725 miles per hour.
So, the plane goes 725 miles in 1 hour i.e. 60 minutes.
Now, we have to find the time the plane takes to fly 150 miles.
As the plane is flying at a constant rate, so we can use the unitary method to get the required time.
Therefore, the plane will take minutes to fly 150 miles. (Answer)
