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

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

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
