Problem 2.9 a runner completes the 200-meter dash with a time of 20.19 seconds. part a what was the runner's average speed in me

Elina [12.6K]

Answer:

Average speed = 9.91 m/s

Explanation :

Total distance covered by a runner = 200 m

Time taken to complete this distance = 20.19 sec

We need to find the average of runner speed in meter/sec

We use the speed, distance, time formula

$speed = \frac{distance}{time}$

speed = $\frac{200}{20.19}$

Average speed = 9.91 m/s

that's the final answer.

I hope it will help you.

Combine and simplify the following radical expression.

guajiro [1.7K]

Answer:

Step-by-step explanation:

$2 \sqrt{20} + 8 \sqrt{45} - \sqrt{80}$

$= 2 \sqrt{2 \times 2 \times 5} + 8 \sqrt{3 \times 3 \times 5} - \sqrt{2 \times 2 \times 2 \times 2 \times 5}$

$= 2(2 \sqrt{5} ) + 8(3 \sqrt{5} ) - (4 \sqrt{5} )$

$= 4 \sqrt{5} + 24 \sqrt{5} - 4 \sqrt{5}$

$= 24 \sqrt{5} (ans)$
