Shannon places 6 packets an equal distance from one another. The distance between the first packet and the sixth packet is 140 cm. If Shannon adds another 11 packets that are equal distance apart,
- How many gaps will there be between the eleventh packet and the seventeenth packet?
- What is the distance between the 11th packet and the 17th packet?
(a)
Number of gaps between 6 packets
= 6 - 1
= 5
Distance between two packets
= 140 ÷ 5
= 28 cm
Number of gaps between the eleventh and the seventeenth packet
= 17 - 11
= 6
(b)
Distance between the eleventh and the seventeenth packet
= 6 x 28
= 168 cm
Answer(s): (a) 6; (b) 168 cm
