Gabby places 4 bags an equal distance from one another. The distance between the first bag and the fourth bag is 120 cm. If Gabby adds another 14 bags that are equal distance apart,
- How many gaps will there be between the fourteenth bag and the eighteenth bag?
- What is the distance between the 14th bag and the 18th bag?
(a)
Number of gaps between 4 bags
= 4 - 1
= 3
Distance between two bags
= 120 ÷ 3
= 40 cm
Number of gaps between the fourteenth and the eighteenth bag
= 18 - 14
= 4
(b)
Distance between the fourteenth and the eighteenth bag
= 4 x 40
= 160 cm
Answer(s): (a) 4; (b) 160 cm
