A rucksack can hold a maximum of 3 kg.
A particular textbook has a mass of 650 g.
What is the maximum number of these textbooks that the rucksack can hold?

Sagot :

Answer:  4 books maximum

Reason:

x = number of textbooks

650x = weight of all x books, at 650 grams each

3 kg = 3000 g

650x = 3000

x = 3000/650

x = 4.615 approximately

Round down to the nearest integer. This is because 4 textbooks weigh 4*650 = 2600 grams = 2.6 kg; while 5 textbooks weigh 5*650 = 3250 grams = 3.25 kg which is over the weight limit.

This means 4 books is the most the rucksack can hold. This is of course only when we have 4 of the same exact book.

4 books!!!!!!! Is the answe
