Problem: Medicines are packed in boxes, each weighing 4kg 400g. How many such boxes can be loaded in a van which cannot carry beyond 800kg.
Solution: 1kg = 1000g
Therefore, 4kg 500g = 4000g + 500g = 4500g
800kg = 800 x 1000g = 800000g
Number of boxes that can be loaded in van = 800000/4500
on dividing, we get quotient as 177 and remainder as 3500
So number of boxes that can be loaded =177 with 3500g spare space
Problem: The distance between the school and the house of a student is 1km 875m.Everyday she walks both ways. Find the total distance covered by her in six days.
Solution: 1km = 1000m
Distance between school and house = 1km 875m = 1000m + 875m = 1875m
Distance covered each day = 1875 x 2 = 3750m
Distance covered in 6 days = 3750 x 6 = 22500m
= 22.5 km or 22km 500m.
