Question

A group of fitness club members lose a combined total of 28 kilograms in 1 week. There are approximately 2.2 pounds in 1 kilogram. Assuming the weight loss happened at a constant rate, about how many pounds did the group lose each day

Answer 1

Answer:

8.8 lbs or 8.8 pounds

Step-by-step explanation:

Weight lose by group of fitness club members in one week = 28kg.

1 week = 7 days.

∴ Weight lost in one day = 28÷7kg=4kg.

Now, ∵ 1kg = 2.2lbs (Given)

∴ 4kg = 4 × 2.2lbs

         =8.8lbs

Answer 2

Answer: 8.8 pounds

Step-by-step explanation:

Given : A group of fitness club members lose a combined total of 28 kilograms in 1 week.

There are approximately 2.2 pounds in 1 kilogram.

Then, the combined weight loss in one week = $2.2\times28=61.6\text{ pounds}$    (1)

Now, we assume that weight loss happened at a constant rate.

Since , 1 week = 7 days    (2)

Then, the number of pounds the group lose each day will be :-

$\dfrac{61.6}{7}=8.8$ pounds    [Divide combined weight in (1) by number of days in week in (2)]

Hence, the number of pounds the group lose each day=8.8 pounds
