Answer 1

Answer:

8cm +3cm means 11 cm

speed =distance divide by time

Answer 2

Answer:

3.6

Step-by-step explanation:

8:3 would be the ratio, to simplify, just add 8 to 3, we will get 11, then divide the answer to the lowest number on the ratio which is 3, if we divide 11 and 3 we will get 3.6... this answer can't be simplified anymore so this will be our main answer for number 1
