Question

a bus covers a certain distance in 3 hours and 20 mins at an average speed of 45 km/h. how long will it take to cover the same distance at a speed of 36 km​

Answer 1

Answer:

Time taken (t) = 3 hours 20 mins

Time taken (t) =  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

⇒ hours.

⇒ 4 hours 10 mins.
