G(x) = 3x - 5
let g(x) = y
y = 3x - 5
y + 5 = 3x
3x = y + 5
x = (y + 5)/3
From y = g(x), x = g⁻¹(y)
<span>x = (y + 5)/3
</span>
g⁻¹(y) = <span>(y + 5)/3</span>
g⁻¹(x) = <span>(x + 5)/3</span>
For c using proportionality of corresponding sides you can writing
(3c+4) 9
--------- = -------
20 15
(3c+4) 3
---------- = ------ cross multiple
20 5
5(3c+4) = 20*3 divide both sides by 5
3c+4=4*3
3c+4=12
3c = 8
c = 8/3
for d you can writing
(2d-3) 9
--------- = ------
12 15
(2d-3) 3
--------- = ------- cross multiple
12 5
5(2d-3) = 12*3
10d -15 = 36
10d = 51
d = 51/10
d = 5,1

Answer:
Faris' arrival time = 3:30 pm + 3 h 54 mnt = 7:24 pm
Step-by-step explanation:
Driving distance between Manchester to London = 195 miles
Coach left Manchester = 3.30 pm
Average speed of coach = 50 mph
Total time taken by the coach to reach the Manchester to London = 195÷50 = 3.9 h
0.9 h = 0.9×60 mnt = 54 mnt
Now,
3.9 h = 3 h 54 mnt
Hence Faris' arrival time in London = 3.30 pm + 3 h 54 mnt = 7.24 pm
