1 kilogram of baking soda costs $4.5

Step-by-step explanation:

To solve this problem, we will follow the steps bellow:

Using proportion;

Let x be the cost of 1 kg of baking soda

kilogram = $ 2

1 kilogram = x

Cross - multiply

× x = $2 × 1

× x = $2

= $2

Multiply both-side of the equation by 9

× 9= $2 × 9

At the left-hand side of the equation 9 will cancel-out 9, hence our equation becomes

4x = $18

Divide both-side of the equation by 4

= $

x = $4.5

1 kilogram of baking soda costs $4.5

Step-by-step explanation:

For a track meet, Tara ran the 1,600 m event at constant speed in 5 minutes and 20 seconds. What was her speed?

Arlecino [84]

Distance ran by Tara = 1600 m

Time taken by Tara to ran 1600 m = 5 min 20 seconds

We have to calculate the speed.

Firstly, we will convert the unit of time in one unit.

Time = 5 min 20 seconds

= 5 min + $\frac{20}{60}$ min (Because 1 min = 60 sec)

= $5+\frac{1}{3}$

= $\frac{15+1}{3}$

= $\frac{16}{3}$ min

Now we will use Distance speed formula which states,

Distance = speed $\times$ time

1600 m = speed $\times$ $\frac{16}{3}$

speed = $\frac{1600 \times 3}{16}$

Speed = 300 m/min

So, the speed of Tara was 300 meter/min.
