• Time taken = 45 minutes

According to the Question -

He covers one half of the distance

(30 mins).

• Balance 3kms are to be covered in 15 minutes.

Speed in kmph will be -

$\\ \implies \sf \: \dfrac{60 \times 3}{15} \\ \\ \\ \implies \sf \: \dfrac{180}{15} \\ \\ \\ \implies \sf \blue{12 \: kmph}$

So,his speed in km per hour will be 12.
