$\large \bold {ANSWER}$

• $\large \boxed { \large \sf \green{ 80 km/h = 22.22 m/s }}$
• $\large \boxed { \large \sf \green{ 120 km/h = 33.33 m/s }}$

$\large \bold {SOLUTION}$

The first thing we must do is convert kilometers to meters. We will do this by multiplying by 1,000, since 1 km corresponds to 1,000 meters.

• 80*1000 = 80,000
• 120*1000 = 120,000

Now that we've done that, let's divide the values by 3,600, because an hour is 60 minutes, and each minute is 60 seconds, so 60*60 is 3,600.

$\frac{80.0\not0\not0}{3.6\not0\not0}=22.22$

$\frac{120.0\not0\not0}{3.6\not0\not0}=33.33$

Hence, 80 km/h = 22.22 m/s, 120 km/h = 33.33 m/s

Answer 2

Detailed Answer:

To convert a value from km/h to m/s and vice versa, we can always use the lengthy formula, but here’s a short version of it which will always come in handy.

• To Convert km/h to m/s
= km/h * 5/18
• To Convert m/s to km/h
= m/s * 18/5

80 km/h to m/s
= 80 * 5/18
= 400/18
=> 22.22 m/s

120 km/h to m/s
= 120 * 5/18
= 600/18
=> 33.33 m/s
