A COMPETITIVE MOTOR RUN.

A motor run was recently arranged by an automobile club, the whole fourteen of the competitors completing the course. The records to hand provide : abundance of material for useful speed problems, but with all the cars they would be somewhat too intricate, so let us take two only of the number, which should test tho reader's thinking power somewhat. One of these cars, X, started oil at 6 o'clock.in tho morning, runfiing 30 miles the first hour, but fell off afterwards four miles hourly. At 10. b 'clock car V started from the same place, travelling along the same route, and covered 50 miles in the first hour, but, as in the case of X, it, too, fell off afterwards by four miles hourly. Now, if both drivers agreed before starting to halt at the 150-mile post from the start until all cars had assembled there, can the .reader say whether V overtook X before arrival at the halting-poiut, and, if so, where and at what time? It is assumed, of course, that the. speed- rates mentioned were unaltered throughout.. ;
