Convert 80 km per hour and 120 km per hour to meters per second​
Burka [1]

hi brainly user! ૮₍ ˃ ⤙ ˂ ₎ა

⊱┈────────────────────────┈⊰

\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
