Yoko places 5 packets an equal distance from one another. The distance between the first packet and the fifth packet is 100 cm. If Yoko adds another 14 packets that are equal distance apart,
- How many gaps will there be between the fourteenth packet and the nineteenth packet?
- What is the distance between the 14th packet and the 19th packet?
(a)
Number of gaps between 5 packets
= 5 - 1
= 4
Distance between two packets
= 100 ÷ 4
= 25 cm
Number of gaps between the fourteenth and the nineteenth packet
= 19 - 14
= 5
(b)
Distance between the fourteenth and the nineteenth packet
= 5 x 25
= 125 cm
Answer(s): (a) 5; (b) 125 cm
