Question 45
Fill in the blanks to make the statements true.
Saturn and Jupiter take 9 hours 56 min and 10 hours 40 min, respectively for one spin on their axes. The ratio of the time taken by Saturn and Jupiter in lowest form is
Time taken by Saturn for one spin = 9h 56min
= (9 × 60 + 56) min [∴ 1h = 60min]
= 596 min
Time taken by Jupiter for one spin = 10h 40min
= (10× 60 + 40) min [∴ 1h = 60min]
= 640 min
Ratio of time taken by Saturn to Jupiter for one spin = 596640
= 149160 [on dividing numerator and denominator by 4]
= 149 : 160
Hence, the ratio of the time taken by Saturn and Jupiter for one spin in lowest form is 149 : 160.
