Question
A person 'X' covered a distance of 'd+40' kilometers at
a speed of 40 km/h, another distance of 'd' kilometers at a speed of 15 km/h, and a third distance of 'd−40' kilometers at a speed of 40 km/h. If the average speed of the entire journey is 18 km/h, determine the value of 'd'.Solution
ATQ, Total distance travelled = d + 40 + d + d – 40 = 3d km So, (3d)/{(d + 40)/40 + d/15 + (d – 40)/40} = 18 Since ‘d’ is eliminated so, we cannot find the value of d.
