All you have to do is the distance divided by the speed, since they didn't mention acceleration, you do 160/30 = 5.33 repeating so just round it and go with B I guess. Hope it helps!

Is there a rate of acceleration? If not then by using the formula time = distance/speed you get 160/30. Which equals 5.333, so I would go with B.

Please helpp<br> What is the area of the purple region? <br> What is the area of the green region?
butalik [34]

what do we need to know:

the radius of the semi circles;

the area of:

  purple region = area of a circle = pi * r^2;

  green region = base * height;

what we know:

the base, 28m;

what the sum of the two diameters is, 28;

the length of a single diameter, 14;

what we can assume:

the two semi-circles are equal, as otherwise i cannot see a way to answer this;

the radius of the two semi-circles, 7m as the two diameters = 28, & d/2 = r

what does that mean:

the height is 17m

green region area = 476 m^2

purple region area is = 153.96 m^2
