Answer:
(x+2) (x+3)
Step-by-step explanation:
To find equivalent numbers you multiply the top and bottom by the same number. Examples are: 2/10 (by 2), 3/15 (by 3), 4/20 (by 4), etc.
1 * 9 = 9
------------
5 * 9 = 45
So another is 9/45

Ok so,
20*2= 40
20*1/2=10
40+10=50
So Johncan travel 50 km in 2 1/2 hours.
