A convertible and a minivan leave a highway junction at the same time. The convertible travels west at 40 miles per hour and the minivan travels north at 50 miles per hour. Assuming the two vehicles do not deviate off course, how far apart are they after 4 hours?

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 = 256 miles.  

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
