Calculate the time it takes for an object moving with a speed of 13m/s to travel 50 m

kykrilka [37]

Answer:

<h3>The answer is 3.85 s</h3>

Explanation:

The time taken can be found by using the formula

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

d is the distance covered

v is the velocity

From the question we have

$t = \frac{50}{13} \\ = 3.846153...$

We have the final answer as

<h3>3.85 s</h3>

Hope this helps you
