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
