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:
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 = [tex]\frac{25}{2}[/tex]
775 = [tex]\frac{25}{2}[/tex] 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
