The amount of time till Rowan and Kennedy would have read the same number of pages is C 6 mins 40 secs.

When will they have read the same number of pages?

Assume that the time they would take to read the same number of pages is x.

Rowan’s reading expression is then:

= 20 + 1.5x

Kennedy is:

= 25 + 3/4x

Equate them:

20 + 1.5x = 25 + 3/4x

1.5x – 3/4 = 25 – 20

0.75x = 5

x = 5/0.75

x = 6.67 minutes

= 6 minutes 40 secs
