Question

Sylvia set a treadmill for 38 minutes, and so far she has run 61% of the minutes. which is the best estimate for the number of minutes sylvia has run so far? 18 minutes 21 minutes 24 minutes 28 minutes

Answer 1

I worked out that 10% of 38 minutes is 3.8 minutes, and then I multiplied by 6 to get 60%. My answer was 22.8 minutes. This is just a rough calculation, but should be close enough for this question.
My asnwer would therefore be: 24 minutes.

Answer 2

Option C, 24 minutes.

Explanation:

Sylvia set a treadmill for 38 minutes,

But she has run only 61% of the time, that she set.

We have to calculate 61% of 38 minutes.

= 61% × 38

`(61)/(100)` × 38

0.61 × 38

= 23.18 minutes

Sylvia ran only 23.18 minutes on treadmill, We have to give the best estimate for the number of minutes so we can say Sylvia ran 24 minutes.
