Car A travels

25\,\text{m/s}

east relative to the road. Car B travels

15\,\text{m/s}

east relative to the road. An observer riding in a truck measures Car A’s speed as

10\,\text{m/s}

east and Car B’s speed as

0\,\text{m/s}

. Determine the truck’s speed relative to the road and state whether the two measurements are mutually consistent.
