an ant starts at one edge of a long piece of paper that is 36.8 cm wide. She travels at 1.8cm/s at an angle of 43 degrees with the long edge.
How long will it take her to get across?
Answer in units of seconds.
I really need help. Please respond ASAP.
Thank you!!
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 = (26.8/sin43°)/1.8 = ______
