A vehicle that is traveling at 94 km/hr travels west from 1:00 p.m. to 3:30 p.m. That's 2 and 1/2 hours of travel time at 94 km/hr. The car will travel 94 km/hr times 2 1/2 hr or 235 km in the time specified. That means the car will be that much farther west than it was at the start, which was 17 km west of a school. Add the distance from the school to the starting point of the vehicle and you'll know where the car will be at the end of the observation period. 235 km + 17 km = 252 km west of the school.

Another car would have to travel at 70 km/hr west.To have the same velocity, it must have the same speed toward the same direction.
If the person sat on the train their velocity relative to the ground would be 95kph. But he/she is goind 3kph to oppose this. So 95-3 = 92 kph to the north is velocity of person relative to the ground.
If you increase the rate of which the projectile was once traveling toward your opponent. A good hard return chap.
