Q.11. The distance between the school and a student’s house is 1 km 875 m. Everyday she walks both ways. Find the total distance covered by her in six days.

Distance covered between school and house
= 1 km 875 m = 1000 + 875 = 1875 m
Hence, distance travelled by the student in one day = 2 × 1875 = 3750 m
Distance travelled by the student in 6 days
= 3750 m × 6 = 22500 m = 22 km 500 m
