Answer:

238 miles

Step-by-step explanation:

340 miles = 5 hours

So get 1 hour by dividing by 5 on both sides

5/5 = 1 hr

340/5 = 68

So in 1 hour they travel 68 miles

You want to find 3 1/2 hours

Do 68 x 3 to get 3 hours

So it would be 68 x 3 =204

Plus the half an hour - which you get by doing 68/2 = 34

<em>68 = 1 hour, so half of that must be half an hour</em>

So to get the final distance you do 204 (3 hours) +34 (half an hour)

204 + 34 =238
