Question

The slowest animal ever discovered is a crab found in the Red Sea that travels an average speed of $5.7km/year$. How long will it take this crab to travel 1 meter? (in minutes)

• A. $90$
  
• B. $91$
  
• C. $92$
  
• D. $93$
  

Answer 1

Answer: (C)

$92$

Speed of the crab $v=5.7km/year$
$⟹v=\frac{5.7\times 1000}{365\times 24\times 60}=1.08\times {10}^{-2}m/min$
Distance to be covered $d=1m$
Time taken $t=\frac{d}{v}=\frac{1}{1.08\times {10}^{-2}}min=92min$
