The answer and the work

Step-by-step explanation:

Let's let $T$ represent the cost of tapes, and $C$ be the cost of CDs.

From the problem statement, we can create the following two equations:

$4T + 2C = 46$

$3T + C = 28$

To solve this system of equations, we can solve for $C$ in the second equation and substitute into the first equation to get the value of $T$ :

$3T + C = 28$

$C = 28 - 3T$

Substitution:

$4T + 2(28 - 3T) = 46$

$4T + 56 - 6T = 46$

$-2T = -10$

$T = 5$

Now that we know the cost of the tapes, we can plug this value into either equation to get the cost of CDs:

$4T + 2C = 46$

$4(5) + 2C = 46$

$20 + 2C = 46$

$2C = 26$

$C = 13$

$3T + C = 28$

$3(5) + C = 28$

$15 + C = 28$

$C = 13$

Therefore, the cost of a tape is $$5$ and the cost of a CD is $$13$ .

In 24 minutes Keisha jogs 2 miles . So in 60 minutes she will jog (2/24) x 60 =5 miles . In 12 minutes she jogs 1 mile . so in 60 minutes it will be 5 miles.
