<h2>Answer:</h2>

Time

<h2>Explanation:</h2>

The average speed of an object that is moving is defined as the distance traveled divided by the time of travel. You can measure the distance with a ruler and the time with a stopwatch. This can be expressed as the following formula:

$v=\frac{\Delta x}{\Delta t}$

For instance, if an object travels a distance $\Delta x=100m$ in 4 seconds, the the average speed is:

$v=\frac{100m}{4s} \\ \\ \therefore \boxed{v=25m/s}$

SEE EXPLANATION

Explanation:

$p = \frac{fd}{t} \\ where \: \\p = power \\ f = force \\ d = distance \\ and \: t = time \\ \\ p = \frac{3800 \times 50}{10} \\ p = \frac{190000}{10} \\ p = 19000w$
