1.	Figure a represents the speed - time graph for a particle . Find the distance covered by the particle between t=10min "and"t=30min
Answer» Solution :We draw perpendicular lines from the 10-minute point and the 30-minute point to the time -axis (Figure b). The DISTANCE covered is EQUAL to area of the RECTANGLE ABCD. It s value is `AB.AD =(30min-10min)xx(10km//h)` =`20minxx10km//h` `h=(20)/(60)hxx10km//h` `=(10)/3km`
