Answer 2

$\huge{\mathcal{Hi\: there!}}$

_______________________

Time taken (t) = 3 hours 20 mins

Time taken (t) = $3 \frac{1}{3} = \frac{10}{3}$ hours.

Speed = 45 km / h.

We know that ;

Distance = Speed × time

⇒ 45 × 10 / 3

⇒ 15 × 10

⇒ 150 km.

Again,

Distance = 150 km.

Speed = 36 km / h.

Now,

Time taken = Distance / Speed

⇒ 150 / 36

⇒ 50 / 12

⇒$4 \frac{2}{12}$ hours.

⇒ 4 hours 10 mins.
