Question

plz solve this question

Answer 1

Distance travelled in x direction =13m
Distance travelled in y direction =14m
so, total distance = 13 i + 14 j
average speed =total distance/total time
so, av. speed=1/5(13 i + 14 j)

Answer 2

its answer is (4) because we konw average velocity is change in displacement/time taken hence its initial displacement is 2i +3j and final is 13i +14j hence it change is 11i+11j or 11(i+j) now put in formulae you get 4 option
