Wendy places 4 bags an equal distance from one another. The distance between the first bag and the fourth bag is 120 cm. If Wendy adds another 15 bags that are equal distance apart,
- How many gaps will there be between the fifteenth bag and the nineteenth bag?
- What is the distance between the 15th bag and the 19th bag?
(a)
Number of gaps between 4 bags
= 4 - 1
= 3
Distance between two bags
= 120 ÷ 3
= 40 cm
Number of gaps between the fifteenth and the nineteenth bag
= 19 - 15
= 4
(b)
Distance between the fifteenth and the nineteenth bag
= 4 x 40
= 160 cm
Answer(s): (a) 4; (b) 160 cm
