The number of students in each of two exercise classes was the same. The box and whisker plots below represent the average amount of time the students in each class spent exercising daily outside class. Based on the information in the box and whisker plots, which statement about the time spent exercising outside of class appears to be true?

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
