Q23 In Hindu chronology, the longest time measure is a para. One para equals 311 040 000 000 000 years. Calculate this value in megayears, hours and in seconds. Write your answers in scientific notation. ​

Sagot :

The conversion in megayears, hours and seconds are :

[tex]1 \: para \: = \: 3.11 \times {10}^{8} \: megayears[/tex]

[tex]1 \: para \: = \: 2.72 \times {10}^{18} \: hours[/tex]

[tex]1 \: para \: = \: 9.81 \times {10}^{21} \: seconds[/tex]

Given that :

1 para = 311040000000000 years

1 mega year = 1 million years :

311040000000000 years expressed in mega years will be :

Let : number of mega years = p

1 mega year = 1,000,000 years

p = 311040000000000 years

Cross multiply :

311040000000000 × 1 = 1,000,000 × p

311040000000000 = 1000000p

p = 311040000000000 / 1000000

p = 311040000 mega years

p = 3.1104 × 10^8 mega years

[tex]1 \: para \: = \: 3.11 \times {10}^{8} \: megayears[/tex]

In hours :

In hours : 8760 hour = 1 year

Let : number of hours = p

1 year = 8760 hours

311040000000000 years = p

Cross multiply :

p = 8760 × 311040000000000

p = 2724710400000000000

p = 2.72 × 10^18 hours

[tex]1 \: para \: = \: 2.72 \times {10}^{18} \: hours[/tex]

In seconds :

31536000 seconds = 1 year

Let : number of hours = p

1 year = 31536000 seconds

311040000000000 years = p

Cross multiply :

p = 31536000 × 311040000000000

p = 9808957440000000000000

p = 9.81 × 10^21 hours

[tex]1 \: para \: = \: 9.81 \times {10}^{21} \: seconds[/tex]
