aleksandrvk [35]

Answer:

<em>Scott will take 221 minutes to run 52 km</em>

Step-by-step explanation:

<u>Speed</u>

The speed of an object can be calculated with the formula:

$\displaystyle v=\frac{d}{t}$

Where d is the distance traveled and t is the time taken.

Scott can run d=20 km in 85 minutes. Thus, his speed is:

$\displaystyle v=\frac{20}{85}\ km/min$

Now he wants to know how many minutes it will take him to run d=52 km. Solving the formula for t:

$\displaystyle t=\frac{d}{v}$

Since the speed has been already determined:

$\displaystyle t=\frac{52}{\frac{20}{85}}$

Multiplying by the reciprocal of the denominator:

$\displaystyle t=52*\frac{85}{20}$

t = 221 min

Scott will take 221 minutes to run 52 km

Cooper bought a serving platter originally priced at $20 but on sale for 50% off. After 10% sales tax, what was the total cost?

Gelneren [198K]

Answ

$11.00

Step-by-step explanation:

A quick way to do this would be as follows: 1.10 ( 0.50*$20), or $11.00.

0.50($20) gives us the sale price (at half off); that's half of $20, or $10.

The total due is then $10 (item cost) plus $1 (tax), or $11
