Marvin says that all rhombuses are squares. Aretha says that all squares are rhombuses. who is correct?

To be a rhombus the quadrilateral must have all equal sides.
To be a square it must have all equal sides AND angles.

Squares are rhombi, but rhombi are not squares. Thus, <u />Aretha is correct.

A van and a truck both drove from Town A to Town B. The distance

Gala2k [10]

First we need to find out the time it took for the truck to reach town B.

$Speed= \frac{Distance}{Time}$

$40= \frac{200}{T}$
$T=5hours$

Now, because the van left 1.5 hours earlier and reached the destination 2.5 hours before, it took 1 hour less the the truck to arrive.

$5hours-1hour=4hours$ which is the time it took for the van to arrive.

Now we use the speed equation again to work out speed.

$Speed= \frac{200}{4}$

$Speed=50mph$ = speed of van

Hope this helped :)
