A car moves at a speed of 80 km / h, and an airplane – 900 km / h. How many times the speed of each of them is less than the first cosmic speed?
The solution of the problem:
The first cosmic velocity of the Earth is 28510.52. In order to find out how many times one number is greater than another,
you need to divide the larger number by the smaller one.
1. Let us find out how many times the speed of the car is less than the first space speed.
28510.52 / 80 = 356.3815 times.
2. Let’s find out how many times the speed of the plane is less than the first space speed.
28510.52 / 900 = 31.678355 times.
Answer: the speed of the car is 356.3815 times less than the first space speed, and the speed of the aircraft is 31.678355 times less.
