Starting at home Omar traveled a pill to the gift store for 30 minutes such as 10 mph event travels back home along the same pat

Dmitry [639]

We know Distance formula is Distance = speed * time

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

Let, the distance Omar traveled = d and speed is 10 miles per hour

Time taken t for the first trip $t = \frac{d}{10}$

Let, the distance Omar traveled = d and speed is 30 miles per hour

Time taken t for the return trip $t = \frac{d}{30}$

Total time taken = $\frac{d}{10} + \frac{d}{30} = \frac{3d+d}{30} = \frac{4d}{30}$

Now, $Average \ speed = \frac{total \ distance}{total \ time \ taken}$

Total distance = d+d= 2d

Average speed = $\frac{2d}{\frac{4d}{30}}$ = $2d * \frac{30}{4d} = 15$

His average speed for the entire trip from home to the gift store and back is

15 miles per hour

Kiran scored 223 fewer points in a computer game than Tyler. Kiran scored 409 points. Which equation would Kiran use to determin

MissTica

Answer:

$t-223=409$

Step-by-step explanation:

Since Kiran scored 223 fewer points in a computer game than Tyler, Tyler's score can be represented as:

$k+223=t$ , where $t$ is Tyler's score and $k$ is Kiran's score.

Since Kiran scored 409 points, we can set $k=409$ :

$409+223=t$ .

Re-arranging this, we get:

$\fbox{$t-223=409$}$ .
