A bus takes 8 houre to cover a distance of 320 km/h what is the average speed of the bus

Answer would be 40 km/hour if distance was written 320 km and total time is 8 hour.Then average velocity=total distance travelled/total time taken=320/8=40km/hour.So the answer is 40 km/hour.Please correct the question first.Write 320 km instead of 30 km/ hour.

For ans time given should be converted into hr and distance in m/sec.then time becomes 480seb and distance becomes 88.8m/sec then avg speed=total dist/time,therefore 88.8/480=0.185m/sec.is the ans.

We can convert these quantity into another another unit at any time either during answer or after getting answer.So the answer also would be 40 km/hr or 100/9 m/ sec.My answer is correct.

Avg.Velocity=total distance/total time.Therefore=--->320Km/8hours.Is equal to=--->40Km/hours.We can convert this answer in m/s according to option

I think there is problems in your question. Form which book you given this question. Please recheck the question
Abid
first of all we convert the units of these given quantities in standard unit(S.I) then by formula we solve it.
data give ;t= 8hours=8×60mins×60secs=28800secs
distance=320km/h=320×1000m=320000m
formula; Vaverage=distance traveled÷time taken
=320000m÷28800sec
=11.11m/s

As we know that ,
average speed=total distance/total time
=320 km / 8 hr
=40 km/hr
note:please correct question at place of “ / “ write per because it seems that you have written km/hr (velocity)
Durwa Thakur
Average speed= 320km/8h.
So, avg speed= 40km/h.
Hope this helps.
Regards.
Btw, in the question you've written 320km/h but it should be 320 km. I've assumed it's 320 km.
