Answer:
10 centimetre / 5 seconds
Step-by-step explanation:
10 cm / 5 sec means that you are travelling 10 cm every 5 seconds. Or 2 cm every 1 seconds. ( Divide by 5).
10 cm / 20 seconds means that you are travelling 10 cm every 20 seconds. Or 0.5 cm ever 1 second. (Divide by 20)

Perimeter of triangle is adding all three sides.
For example a triangle with sides 3, 5, and 7 would have a perimeter of 15
Now we use your values.
632 = (x) + (3x) + (3x + 2)
632 = 7X + 2
630 = 7x
90 = X
So side 1 is 90
Side 2 is 3(90) or 270
Side 3 is 3(90) + 2 or 272
Add all those up and you get (you guessed it) 632
