                The distance between the school and the house of a student's house is 1 km 875 m. Everyday she walks both ways. Find the total distance covered by her in six days.

Answer:

                Given, distance between the school and the house = 1 km 875 m = 1 x 1000 + 875 = 1000 + 875 = 1875 m         [\[\because \] 1 km = 1000 m] \[\therefore \]Distance covered by the student in one day = 2 x 1875 = 3750 m [\[\because \]She walks both ways in one day] \[\therefore \] Distance covered in 6 days = 6 x 3750 = 22500 m = (22 x 1000 + 500) m = 22 km 500 m [\[\because \]1 km = 1000 m]
