ʀᴇǫᴜɪʀᴇᴅ ᴀɴsᴡᴇʀ-:

We know that Speed × Time = Distance

When Speed is $\tt{4}$ kmph and time is $\tt\frac{11}{4}$ hours he covers $\tt{11}$ km.

Therefore when speed is $\tt\frac{33}{2}$ kmph he will take:

$\tt\frac{D}{S}$= $\tt\frac{11×2}{33}$=$\tt\frac{2}{3}$hour or $\tt{40}$minutes to cover the same $\tt{11}$ kms.
