Question

Paul can walk 15 steps in 5 minutes. How long does it take Paul to walk 75 steps at the same speed ?

Answer 1

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
