Kathy places 3 bags an equal distance from one another. The distance between the first bag and the third bag is 130 cm. If Kathy adds another 13 bags that are equal distance apart,
- How many gaps will there be between the thirteenth bag and the sixteenth bag?
- What is the distance between the 13th bag and the 16th bag?
(a)
Number of gaps between 3 bags
= 3 - 1
= 2
Distance between two bags
= 130 ÷ 2
= 65 cm
Number of gaps between the thirteenth and the sixteenth bag
= 16 - 13
= 3
(b)
Distance between the thirteenth and the sixteenth bag
= 3 x 65
= 195 cm
Answer(s): (a) 3; (b) 195 cm
