Answer:okok i know
Step-by-step explanation:dfrac{3}{8}
2. 240 km
Step-by-step explanation:
Anna drives \dfrac{1}{8}, Irina drives \dfrac{3}{8}, Vlad drives \dfrac{1}{8}, then Avel drives
1-\dfrac{1}{8}-\dfrac{3}{8}-\dfrac{1}{8}=\dfrac{8}{8}-\dfrac{1}{8}-\dfrac{3}{8}-\dfrac{1}{8}=\dfrac{8-1-3-1}{8}=\dfrac{3}{8}.
If the road trip involves 640 km of driving, then Avel drives
640\cdot \dfrac{3}{8}=80\cdot 3=240\ km.
Answer:
. \dfrac{3}{8}
2. 240 km
Step-by-step explanation:
Anna drives \dfrac{1}{8}, Irina drives \dfrac{3}{8}, Vlad drives \dfrac{1}{8}, then Avel drives
1-\dfrac{1}{8}-\dfrac{3}{8}-\dfrac{1}{8}=\dfrac{8}{8}-\dfrac{1}{8}-\dfrac{3}{8}-\dfrac{1}{8}=\dfrac{8-1-3-1}{8}=\dfrac{3}{8}.
If the road trip involves 640 km of driving, then Avel drives
640\cdot \dfrac{3}{8}=80\cdot 3=240\ km.
