Question

An airplane flew from San Francisco to Washington, D.C. Approximately

Answer 1

Answer:

The solution is given below:

Explanation:

The computation of the speed is shown below

As we know that

Speed = distance ÷ time

where

distance is 2000 km

And, the time is 2.5 hours

SO, the speed is

= 2,000 ÷ 2.5

= 800 km/h

Now the distance would be the same i.e. 2,000 km

but the time is 2 hours

So, the speed is

= 2,000 km ÷ 2 hours

= 1,000 km/hr

The direction should be opposite to the first airplane
