Question

in 15 days the earth picks up 1.2 x 10^8 kg of the dust from the atmosphere in how many days the earth picks up 4.8 x 10^8 kg of dust​

Answer 1

Answer:

Step-by-step explanation:

In 15 days Earth picks up dust = 1.2×10^8kg.

So, in one kg it took time=15÷1.2×10^8.

So,

In the time taken to pick up 4.8×10^8kg of dust =15÷1.2×10^8.×4.8×10^8kg=60 days

Answer 2

Answer:

The earth picks up$4.8 \times 10^8$ kg of the dust from the atmosphere in 60 days

Step-by-step explanation:

The earth picks up$1.2 \times 10^8$ kg of the dust from the atmosphere in days = 15

The earth picks up 1 kg of the dust from the atmosphere in days =$\frac{15}{1.2 \times 10^8}$

The earth picks up$4.8 \times 10^8$ kg of the dust from the atmosphere in days=$\frac{15}{1.2 \times 10^8} \times 4.8 \times 10^8$

                                =$60$

Hence The earth picks up$4.8 \times 10^8$ kg of the dust from the atmosphere in 60 days
