Sam's step measure :

• 40 cm

Jared's step measure :

• 85 cm

Nia's step measure :

• 90 cm

LCM OF THEIR STEPS :

• 40, 85, 90 : 6120 cm

So, Sam should walk :

• $\frac{6120}{40}$
• $= 153 \: cm$

Jared should walk :

• $\frac{6120}{85}$
• $= 72 \: cm$

Nia should walk :

• $\frac{6120}{90}$
• $= 68 \: cm$
