(Note: In Problems, assume a number like 6.4 is accurate to \(\pm 0.1\); and 950 is \(\pm 10\) unless 950 is said to be “precisely” or “very nearly” 950, in which case assume \(950 \pm 1\). See Section 1–4.)
(II) Two locomotives approach each other on parallel tracks. Each has a speed of \(155\ \mathrm{km/h}\) with respect to the ground. If they are initially 8.5 km apart, how long will it be before they reach each other? (See Fig. 2–35.)
