Respuesta :
I didn't draw a diagram, but this is simple multiplication. 178 x 4 = 712. The boat traveled 712 miles in 4 weeks. (I'm not good with expanded form, but that's the total miles. Get a few more answers that may suggest a good expanded form.)
Answer:
The ferry boat traveled 712 miles in 4 weeks.
Step-by-step explanation:
Ferry boat traveled in one week = 178 miles
It traveled in 4 weeks = 4 × 178
= 4 × (100 + 70 + 8)
= (4 × 100) + (4 × 70) + (4 × 8)
= 400 + 280 + 32
= 712
