Question

Robert climbed 775 steps and 12 1/2 minutes. How many steps did he average per minute?

Answer 1

Answer:

Since the question requires you to give the answer in terms of steps/minute, the first step would be to convert hours to minutes: 12.5 hours = 750 minutes. Next, if he took 775 steps in 750 minutes, how many would he take in 1 minute? This requires you to set up the question as a proportion: (775 steps/ 750 minutes) = (x steps/1 minute)

Step-by-step explanation:

Answer 2

Answer:

Robert climbed  62 steps per minute

Step-by-step explanation:

We can solve this using proportion.

Let x be the number of steps he climbed in a minute

775 steps = 12 1/2  minutes

 x              =  1 minutes

Cross-multiply

775 = 12 1/2 x

But 12 1/2 = $\frac{25}{2}$

775 =  $\frac{25}{2}$ x

Cross-multiply

1150 = 25 x

Divide both-side of the equation by 25

1150/25 = 25x/25

62 = x

x = 62 steps

Therefore Robert climbed  62 steps per minute
