Answer:
It took 2 hours by plane
Step-by-step explanation:
let bus is represented by x and plane is represented by y
the total distance of bus and plane will be represented by equation:
40 x + 600 y = 1320 (1)
the total time taken by bus and plane will be represented by:
x + y = 5 (2)
solving equations (1) and (2) simultaneously:
Multiply by 40 on both sides in eq (2) and then subtract (1) and (2)
40 x + 600 y = 1320
40 x + 40 y = 200
_______________
560 y = 1120
y = 1120/ 56
y= 2
since plane is represented by y so, the time they spent travelling by plane is 2 hours.

Answer:
16
Step-by-step explanation:
![2 \times (4 + (12 + 16) \div 7 \\ (12 + 16) = 28 \div 7 = 4 + 4 = 8 \\ 2 \times 8 = 16](https://tex.z-dn.net/?f=2%20%5Ctimes%20%284%20%2B%20%2812%20%2B%2016%29%20%5Cdiv%207%20%20%5C%5C%20%2812%20%2B%2016%29%20%3D%2028%20%5Cdiv%207%20%3D%204%20%2B%204%20%3D%208%20%5C%5C%202%20%5Ctimes%208%20%3D%2016)
2(z - 5) + (z - 8) =
= 2z - 10 + z - 8 =
= 2z + z - 10 - 8 = <u>3</u><u>z</u><u> </u><u>-</u><u> </u><u>1</u><u>8</u> ← the end
