Two cyclists start from the same point on a mountain. One travels 1200 m downward the mountain in 20 minutes, and the other travels 350 m upward the mountain in the same time. How far are theyfrom each other after 20 minutes? |
| Answer» 850 mStep-by-step explanation:Given :Distance traveled by 1ST CYCLIST in 20 mins = 1200 mDistance traveled by 2nd cyclist in 20 mins = 350 mTo Find :How far are the 2 cyclists from each other after 20 mins = ?Solution :Since they have both started from the same point and are MOVING in opposite directions .Lets ASSUME the downward direction to be positive and upward direction to be negative :So, distance traveled by the 1st cyclist = + 1200 mAnd distance traveled by the 2nd cyclist = - 350 mSo, the gap between them will be = 1200 + (- 350 ) = 1200 - 350 m =850 mSo, after 20 mins they are 850 m far from each other . | |
