Question

a bus can complete its journey in 14 hours with an average speed of 40 km per hour.how long does the bus takes to complete the journey if its average speed is increased to 56 km per hour? whoever answers this with solution gets the brainliest tag.

Answer 1

A bus takes 4.5 hours to complete a complete a journey at a speed of 40km/hr

So, in this case, We will find the distance first because the distance is constant.

distance=speed*time

distance=40*4.5

distance=180km

Now, we find the time to cover the distance at the speed of 45km/hr

time=distance/speed

time=180/45

time=4hrs

Therefore, The answer is 4hrs

Answer 2

Bus travells 14 km at a speed of 40km/hr

If its speed is 56km/hr then distance travelled by bus is (14/40)×56= 19.6km

Time taken by bus to travell 19.6 km in 56km/hr speed is distance /time = 0.35 hr
