Emily places 6 bags an equal distance from one another. The distance between the first bag and the sixth bag is 150 cm. If Emily adds another 11 bags that are equal distance apart,
- How many gaps will there be between the eleventh bag and the seventeenth bag?
- What is the distance between the 11th bag and the 17th bag?
(a)
Number of gaps between 6 bags
= 6 - 1
= 5
Distance between two bags
= 150 ÷ 5
= 30 cm
Number of gaps between the eleventh and the seventeenth bag
= 17 - 11
= 6
(b)
Distance between the eleventh and the seventeenth bag
= 6 x 30
= 180 cm
Answer(s): (a) 6; (b) 180 cm
