Question

Shalini’s house is 7 km 300 m away from school and Alex’s house is 11 km 432 m away from school. Whose house is far and by how much? [4 marks]

Answer 1

Solution:
1 km = 1000 m
Shalini’s house is 7km 300 m away from school=7$\times$1000m + 300m= 7000m + 300 m =7300m [1 mark]
Alex’s house is 11km 432m away from school=11$\times$1000m + 423 m = 11000m+432m =11432m [1 mark]
11432 > 7300 [1 mark]
So Alex house is far away from school
The difference between the distance = Distance from school to Alex's house - Distance from school to Shalini's house = 11432 m -7300 m =4132m.
Alex stays 4132 m far away from school than Shalini. [1 mark]
