After <em>t</em> hours, the first truck covers a distance of (70 km/h) <em>t</em> while the second truck covers a distance of (80 km/h) <em>t</em>. So the distance between them is

(70 km/h) <em>t</em> + (80 km/h) <em>t</em> = (150 km/h) <em>t</em>

They are 900 km apart after

(150 km/h) <em>t</em> = 900 km   ===>   <em>t</em> = (900 km) / (150 km/h) = 6 h

For number 1, add the sides of the triangle. They are all given. The answer is 19.

For number 2, you use the formula for circumference, 2 times pi times radius. The answer is 43.96.

For number 3, I assume that 5 is half of one side. You would double 5 to get ten and multiply it by four, since there are four sides in a square. The answer is 40.

For number 4, you would multiply 5 times pi, but don't solve it. ( since the directions are to leave the answer in terms of pi) The answer is 5 pi.

For number 5, add all the sides together like number 1. The answer is 18.
