Marion places 5 bags an equal distance from one another. The distance between the first bag and the fifth bag is 140 cm. If Marion adds another 12 bags that are equal distance apart,
- How many gaps will there be between the twelfth bag and the seventeenth bag?
- What is the distance between the 12th bag and the 17th bag?
(a)
Number of gaps between 5 bags
= 5 - 1
= 4
Distance between two bags
= 140 ÷ 4
= 35 cm
Number of gaps between the twelfth and the seventeenth bag
= 17 - 12
= 5
(b)
Distance between the twelfth and the seventeenth bag
= 5 x 35
= 175 cm
Answer(s): (a) 5; (b) 175 cm
