Question

The planes LA534 and LA639 are coming in for a landing on the same runway which means they are each lowering their altitude. Note that LA534 is traveling at twice the speed of LA 639. What must they do to keep from crashing into each other on the runway

Answer 1

plane LA534 will have to decrease it speed by twice that of plane LA639.

Step-by-step explanation:

Since both planes want to land there must be a decrease in speed.

We are told that plane LA534 velocity is twice that of plane LA639.

Now for the two planes to land without a crash. the opposite or reverse will be the case in terms of deceleration, that is

Plane LA639 will have to decrease its speed by twice the decrease in speed of plane LA534
