Time Distance and Speed
A passenger train running at the speed of 80 km/h leaves the railway station 6 hour after good train leave overtake it in 4 hour , the speed of good train is ?
Read Solution (Total 10)
-
- let speed of goods train is y km/hr.
distance travelled by goods train in 6 hours=6y km.
relative speed =(80-y)km/hr.
since passenger train overtakes goods train in 4 hours. so,6y=4*(80-y)
so, y=32km/hr. - 10 years agoHelpfull: Yes(10) No(5)
- passenger train travels at a speed of 80 km/h after 6 hours it had traveled distance 480 km(6*80).
but goods traveled same distance in 4 hours .so speed=distance/time (480/4) =120 km/hour. - 9 years agoHelpfull: Yes(7) No(9)
- It is simple problem
Passenger train travel only 4 hours at speed of 80 km/h so total time is 80 * 4 = 320
similarly good train travel 6 hours + 4 hours = 10 hours and distance to cover is 320
simply speed of good train is 320/10 = 32 Answer - 8 years agoHelpfull: Yes(6) No(1)
- Passenger train travels for 4 hr
So distance covered by it= 80*4=320km.
Now good train has traveled for (6+4)hrs=10hr
But covered same distance as passenger train.
So speed of good train=(320/10)=32km/hr - 8 years agoHelpfull: Yes(3) No(0)
- passenger train travels at a speed of 80km/h after 6 covers 480 kmph
goods cross the distance in 4 hours,so distance in 4 hours=480/4=120kmph - 8 years agoHelpfull: Yes(2) No(3)
- Speed of Passenger rain = 80km/h and overtakes goods train in 4 hours
Therefore Distance covered by the Passenger train is = speed * time = 80*4 = 320km
Good Train leave 6 hour before Passenger train hence Time Traveled = 6h
Speed of Good Train = distance/time = 320/6 = 53.3km/h - 8 years agoHelpfull: Yes(0) No(4)
- 120km/hr

- Passenger train travel only 4 hours at speed of 80 km/h so total distance travel is 80 * 4 = 320
let y be the speed of goods train...
And good train travel on that time ( 6 hours + 4 hours) = 10 hours and distance covered is y*10
so speed is 80*4=y*10
320=10y
y= 32 km/h Answer - 8 years agoHelpfull: Yes(0) No(0)
- Passenger train travel only 4 hours at speed of 80 km/h so total distance travel is 80 * 4 = 320
let y be the speed of goods train...
And good train travel on that time ( 6 hours + 4 hours) = 10 hours and distance covered is y*10
so speed is 80*4=y*10
320=10y
y= 32 km/h Answer - 8 years agoHelpfull: Yes(0) No(0)
- 80*4=320km.is the distance traveled to over take goods train.
goods train also travel same distance but in 10h hours
hence speed =320/10=32 km/h - 7 years agoHelpfull: Yes(0) No(0)
