1.	Two cyclists, moving with equal speeds of 10//kmhr, are approaching each other along a straight road. When the distance between them is 20km a fly starting from cycle , keeps on flying alternatively from one cycle to the other. If the fly has a constant speed of 40//hr, find the total distance travelled by the fly before the cyclists meet is
Answer» SOLUTION :Relative velocity of cyclists of approaching =`20km//hr` TIME taken to meet the cyclists`=(20)/(20)=1 HOUR` Distance travelled by fly =`"speed"xx"time"` `=40xx1=40km.`
