Linda places 5 bags an equal distance from one another. The distance between the first bag and the fifth bag is 140 cm. If Linda adds another 13 bags that are equal distance apart,
- How many gaps will there be between the thirteenth bag and the eighteenth bag?
- What is the distance between the 13th bag and the 18th bag?
(a)
Number of gaps between 5 bags
= 5 - 1
= 4
Distance between two bags
= 140 ÷ 4
= 35 cm
Number of gaps between the thirteenth and the eighteenth bag
= 18 - 13
= 5
(b)
Distance between the thirteenth and the eighteenth bag
= 5 x 35
= 175 cm
Answer(s): (a) 5; (b) 175 cm
