Step-by-step explanation:
1. you have to make a proportion
The proportion is 15 steps/ 5 minutes
2. Next you have to find the variable in the next proportion, so the variable would be the number of minutes
So the proportion would look like 75 steps/ “ x” minutes
3. Solve. 15 steps/ 5 minutes= 75 steps/ “ x” minutes (Cross multiply)
15x=5x75
15x=375
x=25
4. So the answer is 25 minutes to walk 75 steps
