Given the speed is 200 km /hr


use 1 km  = 1000 meter

1 hr = 3600 seconds

so

200 km/hr = \frac{200*1000}{1*3600}   m/s

simplifies to

\frac{5000}{9} m/s

55.6 m/s

so option C

Answer:  C) 55.6 m/s  

Step-by-step explanation:  200km/1hr x 1000m/1km x 1hr/60min x 1min/60s = 55.6 m/s

If the conversion factors are properly set up and all numbers are correct, the unwanted units cancel out leaving the units of the final answer.

Answer:

Yes, because the x's do not have more than one y.

Step-by-step explanation:

x      y

0      0

5       10

6       12

10     20

(That's meant to be a table). Looking at the x and y table values, you can see that none of the x's have two y's. So, this relation is a function.
