Question

Intr-un minut, un melc parcurge 300 mm, iar o rama de 3 ori mai mult. Ce distanta parcurge melcul in 4 minute? Dar in 5 minute? Ce distanta parcurge rama in 4 minute? Dar in 7 minute?

Answer 1

in 4 minute 
4x300=1200mm
in 5 minute
5x300=1500mm

rama parcurge in 4 minute
300x3x4=3600mm

in 7 minute
300x3x7=6300mm

Answer 2

MELCUL :
 
1 min = 300 mm 
300 × 4 = 1200 ( 4 minute )
300 × 5 = 1500  (  5 minute )

RAMA : 

1 min = 300 × 3 = 900 mm
900 × 4 = 3600 ( 4 minute )
900 × 7 = 6300 ( 7 minute )
