Question:
Lisa walks at an average speed of 6 km/h for 15 hours.
Dan completes the same distance in an hour. Calculate Dan's average speed.
Answer:
Step-by-step explanation:
Given
Lisa:


First, we calculate the distance covered by Lisa:



So, Dan distance can be represented as:
--- Dan completes the same distance as Lisa
-- Time to complete the distance
Dan's average speed is:



<em>Hence, Dan's average speed is 90km/hr</em>
3, 6, 9, 12, 15

A good place to start for this question is to define the properties of the geometric terms you are given.
Quadrilaterals have four straight sides.
Parallelograms are quadrilaterals that have two pairs of parallel sides. The opposite sides and opposite angles are congruent. Squares, rectangles, and rhombuses are examples of parallelograms.
Trapezoids are also quadrilaterals. They have only one pair of parallel sides.
So we're looking to see if there are any four-sided shapes that can be made with no parallel sides. The attached picture shows an example of a quadrilateral that is not a parallelogram and is not a trapezoid. Based on these properties of polygons, the correct answer is B.
