If Karen rode her bicycle 5 km to school in 30 minutes, what was her average speed? Give your answers in km/h.

Doss [256]

Answer:

10 km/h

Explanation:

Before calculating the average speed, we need to convert the time taken for the trip from minutes to hours. Since 1 hour cointains 60 minutes, we have:

$1 h: 60 min = t : 30 min\\t=\frac{1 h \cdot 30 min}{60 min}=0.5 h$

Karen's average speed is given by:

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

where

d = 5 km is the distance covered

t = 0.5 h is the time taken for the trip

Substituting into the equation, we find

$v=\frac{5 km}{0.5 h}=10 km/h$

You have a large flashlight that takes 4 D-cell batteries, each with a voltage of 1.5 volts. If the current in the flashlight is

Naddik [55]

Ohm's law states that,
V = I x R
where V, I, and R are voltage, current, and resistance, respectively. Rearranging the equation gives,
R = V / I
Replacing the variables with the given values,
R = 1.5 volts / 2.0 amp
The answer is letter B. 0.75 ohms.
