Question

Can someone help me with question 10 plz due tmrw

Answer 1

what I understand is that the seconds/ meters, so you would do
62.592/400=.15648 per meter
.15648*100=15.648

Not sure if I did it right but at least you have an answer. :)

Answer 2

if you divide 62.592 by 4 you get the answer of 15.648 seconds for 100 meter
