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.
Answer: x = 3
Step-by-step explanation: First subtract 2x from both sides to get:
3x + 6 = 15
Then subtract 6 on both sides
3x = 9
Now divide by 3 to isolate x to get...
x = 3
