Two marathon runners run the full distance of the marathon, approximately 26 miles, in 4 hours.
xxTIMURxx [149]

Answer:

6.5 miles in 1 hour and they will run 75% of the full distance in 1 hour.

Step-by-step explanation:

The distance covered by two marathon runners = 26 miles

They takes 4 hours

We need to find how many miles did they run in 1 hour

In 4 hour, the distance covered is 26 miles

To find distance covered in 1 hour, divide 26 by 4 such that.

d=\dfrac{26}{4}\\\\d=6.5\ \text{miles/hour}

So, they will cover 6.5 miles in 1 hour.

For percentage,

\%=\dfrac{26-6.5}{26}\times 100\\\\=75\%

So, they will run 75% of the full distance in 1 hour.

Multiply.
ANTONII [103]

The multiplication of the expression (x² + 3x + 2) (2x² + 3x + 1) is 2x⁴ + 9x³ + 14x² + 9x + 2

<h3>Multiplication</h3>

(x² + 3x + 2) (2x² + 3x + 1)

= 2x⁴ + 3x³ + x² + 6x³ + 9x² + 3x + 4x² + 6x + 2

  • collect like terms

= 2x⁴ + 3x³ + 6x³ + x² + 9x² + 4x² + 3x + 6x + 2

= 2x⁴ + 9x³ + 14x² + 9x + 2
