A=(v+w)(k-x), for x <br><br> I would appreciate it if you included the steps for solving it too!!!!

Anna71 [15]

Step-by-step explanation:

$a=(v+w)(k-x)$

$(k - x) = \frac{a}{(v + w)}$

$x = k - \frac{a}{v + w}$

$x = \frac{kv + kw - a}{v + w}$

A circular running track is 1/4 mile long. Jamie runs on this track, completing each lap in 1/20 of an hour. What is Jamie’s run

Grace [21]

Answer: The running speed of Elena is 5 miles/hour and this can be determined by using the formula of speed.

Step-by-step explanation:

A circular running track 1/4 is a mile long.

Elena runs on this track, completing each lap in 1/20 of an hour.

Speed formula is used to determine the speed of Elena. The formula of speed is given by:

----- (1)

where S is the speed, D is the distance and T is the time taken by Elena to run a circle.

Now, put the value of distance D and time T in the equation (1).

Speed = 5 miles/hour

Therefore, the running speed of Elena is 5 miles/hour.
