Question 857691: It is 185 km from city A to city B. If a bus takes 2 hours to cover the first 85 km, how long must it take to travel the final 100 km in order to average 50 kmph for the entire trip Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! It is 185 km from city A to city B. If a bus takes 2 hours to cover the first 85 km, how long must it take to travel the final 100 km in order to average 50 kmph for the entire trip
Time taken at average 50 km/h = 185/50 = 3.7 hours
time taken for 85 km = 2 hours
time taken for next 100 km = 100/x
where x is the speed
2+100/x= 3.7
2x+100=3.7x
1.7x= 100
x= 58.82 km/h
