a. 40
b. 72
c. 80
d. 100
e. 120

Option E.

Step-by-step explanation:

Let the intended length of Rebecca's swimming is = x units

and we assume the length of the pool = l units

Now it is given in the question that " She covers one fifth of her intended distance "

That means distance covered =

" After swimming six more lengths of the pool she had covered one quarter of her intended distance"

So

x = 20×(6l)

x = 120l

Therefore, Rebecca has to complete 120 lengths of the pool.

Option E is the answer.
