Emily places 6 bags an equal distance from one another. The distance between the first bag and the sixth bag is 100 cm. If Emily adds another 12 bags that are equal distance apart,
- How many gaps will there be between the twelfth bag and the eighteenth bag?
- What is the distance between the 12th bag and the 18th bag?
(a)
Number of gaps between 6 bags
= 6 - 1
= 5
Distance between two bags
= 100 ÷ 5
= 20 cm
Number of gaps between the twelfth and the eighteenth bag
= 18 - 12
= 6
(b)
Distance between the twelfth and the eighteenth bag
= 6 x 20
= 120 cm
Answer(s): (a) 6; (b) 120 cm
