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 l. Assuming the weight loss happened at a constant rate, about how many pounds did the group lose each day?

8.8 pounds.

Step-by-step explanation:

Hi, to answer this question, first we have to divide the total weight loss in a week (28 kg) by 7 (days in a week).

28 /7 = 4 kg per day

The group lost 4 kg each day.

Finally we have to convert the result into pounds.

Since 1 kg = 2.2 pounds

4 kg x 2.2 = 8.8 pounds.

Feel free to ask for more if needed or if you did not understand something.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
