Jen places 4 bags an equal distance from one another. The distance between the first bag and the fourth bag is 120 cm. If Jen adds another 12 bags that are equal distance apart,
- How many gaps will there be between the twelfth bag and the sixteenth bag?
- What is the distance between the 12th bag and the 16th bag?
(a)
Number of gaps between 4 bags
= 4 - 1
= 3
Distance between two bags
= 120 ÷ 3
= 40 cm
Number of gaps between the twelfth and the sixteenth bag
= 16 - 12
= 4
(b)
Distance between the twelfth and the sixteenth bag
= 4 x 40
= 160 cm
Answer(s): (a) 4; (b) 160 cm
