Question
$A$ is twice as fast as $B$ and $B$ is thrice as fast as C. If some distance is covered by $\mathrm{C}$ in 54 minutes, then in how much time will $B$ cover?(a) 9 minutes(b) 18 minutes(c) 12 minutes(d) 15 minutes
Step 1
Since B is thrice as fast as C, the speed of B will be \( 3v \). Show more…
