Answer:

No, there is no proportional relationship

Step-by-step explanation:

The proportional relationship is:

y = kx, which is a special form of linear equation, with zero y-intercept

In the given case we have:

y = 4.5x + 10

This is a linear function but not proportional relationship because it has y-intercept, different than zero

Convert 80 km per hour and 120 km per hour to meters per second

Burka [1]

$\large \bold {ANSWER}$

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

$\large \bold {SOLUTION}$

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.

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