Answer:
Speed= 50km/hr
Time taken= 4 hours
Distance= Speed*Time
Therefore Distance= 50*4=200kmThe question is that how much time will the bus take to complete 200 km when it travels at 10kmph less speed
So new speed= 50km/h-10km/hr= 40km/hr
Distance= 200km
Time= Distance/Speed
Therefore Time= 200/40= 5hours
Answer is 5 Hours
