Question

A ferry boat travels 178 miles in one week. How many miles does the boat travel in 4 weeks? Draw a diagram and use expanded form to solve

Answer 1

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 2

The ferry boat traveled 712 miles in 4 weeks.

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
