Answer:
x = 6
Step-by-step explanation:
6 x 2 = 12
1 meter=100 centimeters so 1.5 meter times 100 centimeters which is 150 centimeters so the answer is 225-75=150 centimeters.
12:4 can be simplified to 3:1, so now you have 3 kilometers per every 1 hour, you need to know how many kilometers she can do in 6 hours, so you just multiply 3 by 6 which is 18. As a ratio it would be 18:6.
