Question

two bugs A and B are travelling along a meter scale A and B are at 50 cm and 40 cm respectivilely after 2minutes they are at 40 cm and 25 cm marks respectively time required for bug A travel from 50 cm mark to 25 cm mark is
​

Answer 1

Answer:

Distance travelled by bug A in 2 minutes is 

(50−40)=10 cm and Distance travelled by 

 bug B in 2 minutes is (40−25)=15 cm

 speed of bug A=10/2=5 cm/min . 

 Now distance travelled by bug A is 

(50−25)=25 cm

 So time required by bug A=525=5 min
