Let '$x$' hours be the time that I travelled at 40 kmph
Therefore, $5–x$ hours would be time that I travelled at 60 kmph.
Hence, I would have covered $x\times 40+(5−x)60$ kms in the 5 hours = 240 kms.
Solving, for $x$ in the equation $40x+(5–x)\times 60=240$, we get
$⇒ 20x=60$ or $x$= 3 hours
Two men are walking towards each other alongside a railway track. A freight train overtakes one of them in 20 seconds and exactly 10 minutes later meets the other man coming from the opposite direction. The train passes this man is 18 seconds. Assume the velocities are constant throughout.
Moderate Time, Speed & Distance Question - 13
Common Information Question: 1/2
