Assuming that each runs with uniform speed,find when they meet.A rectangular field ABCD,in which AB=4BC,is crossed obliquely by a staight path that cuts PB in Pand DC in Q. If the ratio AP: BP is 1: 3.and the ratio of the area APQD to the area PBCQ is 5: 7,find the ratioDQ: QC. If the length of the path is 100 yard find the dimensions of the field. |
