Answer:
The airplane is cruising at 200 metres per second.
Step-by-step explanation:
The speed of the object can be got by dividing the distance it travelled by the time taken to travel that distance.
For us to get the accurate cruising speed, we will have to convert all units to their S.I form
Distance - 1 kilometer = 1 X 1000 metres = 1000 metres
1/12 of a minute = 1/12 X 60 = 5 seconds.
Therefore the speed = distance / time
= 1000/5 = 200m/s
The airplane is cruising at 200 metres per second.
The number is 5. All you have to do is make an equation based on the information you have, x will represent the missing number so, x to the power of 10 divided by x to the power of 7 is equal to 125, then solve.
Answer:
B
Step-by-step explanation:
We can get two equations from the inequality:

We just need to simplify both equations to get our answers:


The two answers we get are:

Which is also B.
