An ant starts at one edge of a long strip of
paper that is 36.8 cm wide. She travels at
1.8 cm/s at an angle of 43◦ with the long edge.
How long will it take her to get across?
Answer in units of s
Pls I need the answer
Thank you!
as I told you yesterday,
If you draw a diagram, you can see that the distance she travels (d) is given by
36.8/d = sin43°
now, knowing d, use the fact that time = distance/speed, so
t = (36.8/sin43°)/1.8 = ______
