Distance equals Rate times Time: d=rt, so Rate equals Distance divided by Time r=d%2Ft and Time equals Distance divided by Rate t=d%2Fr.

First calculate the rate for the first part of the trip: r=26%2F4.

Second, take the result of the previous calculation, divide it by 2, and replace r in t=10%2Fr with that result. Then do the arithmetic.
