**Answer:**

**Step-by-step explanation:**

The problem, in part, that you are having is that you are giving fractions for answers and they want miles.

1 whole trip = 1000 miles

3/8 of a trip = x miles.

You have a proportion

1/(3/8) = 1000/x Cross multiply

1 *x = (3/8) * 1000 Combine of the left. Multiply on the right.

x = 3/8 * 1000

x = 3000 / 8

x = 375 miles.

If Ryan has already driven 375 miles, then how many miles remain?

James faces 1000 - 375 = 625 miles.

James wisely decided that he is only going to drive 2/5 of what is left.

625 * 2/5 = 1250/5 = 250 miles.

Answer

Ryan 626 miles

James 250 miles
