Question

a bus covers a certain distance in 3 hours 20 minutes at an average speed of 45 kilometre per hour how much time will it take to cover the same distance at a speed of 50 km per hour

Answer 1

Answer:

Step-by-step explanation:

D=x

T=3 hr 20 min

Answer 2

initiatially ,average speed= 45km/ hr

time taken = 3hr 20min

= 3hr + 20/ 60 hr = 3 + 1/ 3 = 10/ 3 hr


distance = speed × time

= 45 × 10 /3= 150 km


new speed = 50km/ hr


time taken to cover the same distance

= distance/ new speed

= 150 / 50 = 3 hr


Answer:

it will take 3 hr to cover the same distance
