Raman had to cover a distance of 30 km to reach his grandmother's house.He covered 11.25 km by bus,7.083 km by auto and rest by foot.(a) How much distance did Raman cover by foot?(7th class math)

Solution:

Given,

 Total Distance of Raman grandmother's house = 30 m

  Raman covered by Bus = 11.25 km

                            by auto = 7.083 km

                            by foot = ?

  Let Raman covered by foot = x

  then according to question,

  Total distance = covered by(Bus + Auto + Foot)

                 30    = 11.25 + 7.083 + x

                 30    = 18.333 + x

      30 - 18.333 = x

                      x = 11.667

  Therefore,Raman distance covered by foot 11.667 km.
