The speed of plane 1 will be 300 miles/sec and that of plane 2 will be 600 miles/sec.

We have two planes flying in opposite directions to each other.

We have to determine how fast was the each plane flying.

<h3>What is the formula to calculate the distance covered by the object moving with speed -  x m/s  in time -  t s ?</h3>

The formula to calculate the distance travelled will be -

distance = speed x time = (xt) meters

According to the question -

Let us assume that the speed of plane 1 =  v miles/sec.

Then, the speed of plane 2 will be = 2v miles/sec.

Distance covered by plane 1 in 3 hours will be = 3v miles.

Distance covered by plane 2 in 3 hours will be = 3 x (2v) miles = 6v miles.

Since they are 2700 miles apart after three hours, therefore -

3v + 6v = 2700

9v = 2700

v = 300 miles/sec

Hence, the speed of plane 1 will be 300 miles/sec and that of plane 2 will be = 2v = 2 x 300 = 600 miles/sec.

34kurt

Answer:

1/6

Step-by-step explanation:

Starting with 2 cubes that have 6 numbers total for each one, so 2 cubes will have 12 numbers total, and the probability of number 5 is 2/12 (because each cube has a number 5, so two cubes will have 2, and fraction for it will be 2/12). After simplification, the final result is 1/6.
