After 4 hrs, the vehicles traveled 256 miles.
Explanation:
Two vehicles traveling at a rate of 40 and 50 miles per hour.
A convertible and a minivan leave a highway junction at the same time.
The convertible travels west at 40 miles per hour = (40/ hr) / 4 = 160 miles
the minivan travels north at 50 miles per hour = (50/hr) / 4 = 200 miles
how far apart are they after 4 hours is [tex]\sqrt{160^{2} + 200^{2} }[/tex] = 256 miles.
