Answer: x = 3, -5
<u>Step-by-step explanation:</u>
2 |x + 1| + 3 = 11
<u> -3</u> <u>-3 </u>
2 |x + 1| = 8
<u>÷2 </u> <u> ÷2 </u>
| x + 1 | = 4
x + 1 = 4 or x + 1 = -4
<u> -1</u> <u>-1 </u> <u> -1 </u> <u> -1 </u>
x = 3 or x = -5
We Know That,
![speed \: = \frac{distance}{time}](https://tex.z-dn.net/?f=%20speed%20%5C%3A%20%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D%20)
Hence,
![time \: = \frac{distance}{speed}](https://tex.z-dn.net/?f=time%20%5C%3A%20%20%3D%20%20%5Cfrac%7Bdistance%7D%7Bspeed%7D%20)
According to given,
speed = 783 km/h
distance = 8352 km
Therefore,
![time \: = \frac{8352}{783}](https://tex.z-dn.net/?f=time%20%5C%3A%20%20%3D%20%20%5Cfrac%7B8352%7D%7B783%7D%20)
time = 10.6
time = 10hr 40mins
Now,
Also given that-
plane leaves at 9hr 52mins local time
hence,
time = 10hr 40mins + 9hr 52mins
time = 20hr 32mins
But,
plane is 2hrs behind
Therefore,
time = 20hr 32mins - 2hrs
time = 18hrs 32mins
What is speed?
Speed is defined as :
The rate of change of position of an object in any direction.
Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.
Speed Formula
The formula of speed is given in the table below:
s = d/t
where,
- s is the speed in m.s^(-1)
- d is the distance traveled in m
this is the time taken in s

Answer: 2.456 x 10 to the power 11
Step-by-step explanation: Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10
. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
