Penelope places 6 bags an equal distance from one another. The distance between the first bag and the sixth bag is 150 cm. If Penelope adds another 10 bags that are equal distance apart,
- How many gaps will there be between the tenth bag and the sixteenth bag?
- What is the distance between the 10th bag and the 16th bag?
(a)
Number of gaps between 6 bags
= 6 - 1
= 5
Distance between two bags
= 150 ÷ 5
= 30 cm
Number of gaps between the tenth and the sixteenth bag
= 16 - 10
= 6
(b)
Distance between the tenth and the sixteenth bag
= 6 x 30
= 180 cm
Answer(s): (a) 6; (b) 180 cm
