Answer» Answer:let the distance travalled be x then (x/80+x/60)-2x/60=2 hour so by solving x=480 km8 years agoHelpfull: YES(20) No(3)let distance=x 2x/60-(x/80+x/40) =240 for going ence for to & fro 2*240=4807 years agoHelpfull: Yes(3) No(0)ans=480 480/60=8hr up and down so 16hr 480/80=6hr for up 480/40=12hr for down so 18 hr 8 years agoHelpfull: Yes(2) No(1)480 km. If Distance between Delhi and Patna= x km. then Round TRIP time TAKEN with speed of 60 kmph= 2x/60 Time taken when travelled from Delhi to Patna @80 kmph and back from Patna to Delhi @40 kmph=(x/80)+(x/40) As later time is 2 hours more than previous, so (2x/60) +2 =(x/80) + (x/40) On solving x=480 Hope it helped if so then pls MARK as brainlist thank you |
