Question

$A$ is twice as fast as $B$ and $B$ is twice as fast as $C$. The distance covered by $C$ in $54$ min will be covered by $A$ in

• A. $216$ min
• B. $27$ min
• C. $108$ min
• D. $13.5$ min

Answer 1

Answer: (D)

$13.5$ min

According to the question

$A=2B$

$B=2C$

$\because$ C takes 54 minute the B takes half of the time$=\frac{54}{2}=27min$

if B takes 27 min then A takes half of the time$=\frac{27}{2}=13.5min$
