A. 65 sec B. 89 sec
C. 100 sec D. 150 sec
Read Solution (Total 4)
-
- speed=240/24=10m/sec
total distance=240+650=890m.
time=890/10=89sec. - 12 years agoHelpfull: Yes(2) No(1)
- speed=240/24=10m/sec
total distance=240+650=890m.
time=distance/speed
speed=distance/time
10=890/(24+x); //where x is the time to pass the platform
then x=65

- speed= 10 m/s
so time required to cross the platform = (240+650)/10

- Speed = 240 m/sec /24= 10 m/sec.
Required time = 240 + 650/10 sec = 89 sec. - 6 years agoHelpfull: Yes(0) No(0)
