we know that speed =distance/time
speed=240/3 kmph or 80 kmph
speed is increase by 50% so new speed=
80 ×150/100=80×3/2=120 kmph.
now again,
speed=distance /time
120kmph=300kmph/time
time=300/120 kmph =5/2 hr or 2hr 30 min
speed=240/3 kmph or 80 kmph
speed is increase by 50% so new speed=
80 ×150/100=80×3/2=120 kmph.
now again,
speed=distance /time
120kmph=300kmph/time
time=300/120 kmph =5/2 hr or 2hr 30 min
