the speed rate is simply obtained by dividing the meters by the seconds.

so Tawni did 50 meters in 40.8 seconds, that means her speed rate is 50/40.8 or about 1.23 m/s.

Pepita did 100 meters in 60.2 seconds, so she's 100/60.2 or about 1.66 m/s.

Susana did 200 meters in 112.4 seconds, so she's about 1.78 m/s.

the one who ran the fastest is the one who covered more meters in 1 second.

Find the volume of the triangular prism in the picture shown. Round your answer to the

Olenka [21]

Given:

A figure of a triangular prism.

Height of triangular base = $9\dfrac{2}{3}$ yd

Base of triangular base = 4 yd

Height of prism = 4 yd.

To find:

The volume of the triangular prism.

Solution:

Volume of a triangular prism is:

$V=Bh$ ...(i)

Where, B is the area of triangular base and h is the height of the prism.

Area of triangular base is:

$B=\dfrac{1}{2}\times base\times height$

$B=\dfrac{1}{2}\times 4\times 9\dfrac{2}{3}$

$B=2\times \dfrac{29}{3}$

$B=\dfrac{58}{3}$

Putting $B=\dfrac{58}{3}$ and h=4 in (i), we get

$V=\dfrac{58}{3}\times 4$

$V=\dfrac{232}{3}$

$V=77.33...$

$V\approx 77.3$

The volume of the triangular prism is 77.3 cubic yards. Therefore, the correct option is 2.
