You find the litres of petrol you want and go up until you find where the line crosses this point and then see how far you can travel on the left so
a is 15km
and b is 39km
21*x= 7
Trying to find x
21*x= 21x
21x= 7
divide by 21 for both sides
21/21x= 7/21
cross out 21 and 21, divide by 21 . Then 1*1*x= x
x= 1/3
Answer : 21*1/3= 7
So five pages of her fiction book in 7 minutes. And she must read thirty pages:

15 * 7 = 105 minutes for the history textbook
Add:
42 + 105 = 147 minutes.
