      Atul takes ‘h’ hours to travel (1/5)ᵗʰ of the

      total distance at a speed of 12 km/h. If he had travelled the entire distance at an average speed of 15 km/h, the journey would have taken him (h + 6) hours. Determine the value of ‘h’.

      Solution

      ATQ,

      Let total distance be ‘d’ km

      So, 12 = (d/5h) -------- (I)

      And, 15 = {d/(h + 6)}-------- (II)

      By equating equation (I) and equation (II), we get,

      12 × 5h = 15 × (h + 6)

      Or, 12h = 3(h + 6)

      Or, 9h = 18

      Or, h = 2
