A car is driving at 100 kilometers per hour. How far does it travel in 2 seconds?

Alisiya [41]

Answer:

$\frac{1}{18}\ km$ or $\frac{500}{9}\ m$

Step-by-step explanation:

Remember that

1 hour=3,600 seconds

by using proportion

$\frac{100}{3,600}\frac{km}{sec} =\frac{x}{2}\frac{km}{sec} \\ \\x=2*100/3,600\\ \\x=\frac{1}{18}\ km$

Convert to meters

$(1,000)*(\frac{1}{18})=\frac{500}{9}\ m$

Complete the puzzle by clicking on the puzzle piece that contains equivalent expression.

Liono4ka [1.6K]

Answer:

-5 when ...

Step-by-step explanation:

The rules of exponents can help you simplify the given product.

<h3>Rules</h3>

(a/b)^c = (a^c)/(b^c)

(ab)^c = (a^c)(b^c)

(a^b)(a^c) = a^(b+c)

(a^b)/(a^c) = a^(b-c)

<h3>Application</h3>

$\left(\dfrac{x}{y}\right)^2(-x^2y)^3=\\\\\dfrac{x^2(-1)^3(x^2)^3y^3}{y^2}=-x^{2+2\cdot3}y^{3-2}=-x^8y$

This expression does not match any of those offered.

When x=-1 and y=5, this becomes ...
