The coach will leave Manchester at 3.30 pm
Faris assumes that the coach will travel at an average speed of 50 mph
a) Using his assumption, work out Faris's arrival time in London,
It actually turns out that the coach has a lower average speed,
b) Describe how this affects the arrival time,

goog may be able to you find that answer

the correct answer is x/3+10≥32

hope this !

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

-9
