Zara places 5 bags an equal distance from one another. The distance between the first bag and the fifth bag is 120 cm. If Zara adds another 10 bags that are equal distance apart,
- How many gaps will there be between the tenth bag and the fifteenth bag?
- What is the distance between the 10th bag and the 15th bag?
(a)
Number of gaps between 5 bags
= 5 - 1
= 4
Distance between two bags
= 120 ÷ 4
= 30 cm
Number of gaps between the tenth and the fifteenth bag
= 15 - 10
= 5
(b)
Distance between the tenth and the fifteenth bag
= 5 x 30
= 150 cm
Answer(s): (a) 5; (b) 150 cm
