if a bus with an average speed of 45 km per hour takes 10 hrs to travel from a place to other in how many hour the bus can travel from one place to other if speed is increased by 5 km per hour

9 Hours

Step-by-step explanation:

If it is increased by 5 km that would make it 50. But, let's go back to the 45 to find out how many km we are traveling. If we are doing 45 km per hour then you just multiply the 10 by 45 and get 450 km. Now that we have that, if the new speed is 50 km per hour, all we need to do is 450 divided by 50, which will get you 9.
