Answer 1

Answer:

I don't understand the question

Answer 2

Question :

➡ What is the speed of a rocket that travels 8000m in 13s?

To find:

➡ speed=?

Given values :

➡ distance =8000m

➡ time =13s

Formula :

➡ $\begin{gathered}\\ \large\boxed{\sf{Speed=\dfrac{Distance}{time}}}\end{gathered}$

Solution :

$\begin{gathered} \\ \implies \large \sf \: speed \: = \frac{distance}{time} \end{gathered}$

$\begin{gathered} \\ \implies \large \sf \: speed \: = \frac{8000}{13} \end{gathered}$

$\begin{gathered} \: \: \: \: \: \: \: \: \: \\ \: \: \: \: \: \: \large \blue \bigstar\boxed{ \underline{ \underline {\bf{speed \: = 615.38 \: \frac{m}{s} }}}}\end{gathered}$

Now Converting m/sec into km/hr

Step 1:

Multiply 615.38 by 18

We have 615.38 * 18 = 11076.84

Step 2:

Divide 11076.84 by 5

11076.84/5 = 2215.368

Final Answer:

615.38 m/sec = 2215.368 km/hr
