An ant crawls towards a mirror by 0.67 cm/s, then at what speed will the ant and ant’s image come nearby to each other in one second? Correct Answer 1.34 cm/s
In 1 sec, the ant moves by 0.67cm towards the mirror. As the ant moves, ant’s image will also move simultaneously hence, by that time only the image will also move by 0.67cm. This means, in total in that one sec, the ant and ant’s image closer by (2 × 0.67 cm) = 1.34 cm.
