Every day, about 140,000,000 plastic water bottles are bought in the united states. each bottle is about 0.25 meters long, and the equator of the earth is about 40,000,000 meters around.

how many times can the earth's equator be circled by a line of plastic bottles used in the united states every day?

0.875 times Earth's equator is circled by plastic bottles every day.

Step-by-step explanation:

Given: No of plastic water bottles every day = 140,000,000

           Length of a bottle = 0.25 m

           length of equator of earth = 40,000,000 m

To find: no times Earth's equator is circled by line of bottles every day

No of plastic water bottles every day = 140,000,000

Length of 1 plastic water bottle = 0.25m

⇒ Length of 140,000,000 plastic bottles = 0.25 × 140000000

                                                                    = 35000000 m

No. of times Earth's Equator is circled by bottles =

                                                                                = 0.875

Therefore, 0.875 times Earth's equator is circled by plastic bottles every day.

the answer is 24

step-by-step explanation:

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.
