Heyoo. Hope this helps you understand why is the answer is option 2. If you still don’t understand, feel free to ask for me to further explain. I used two important rules to figure it out (they are included in the picture).
Answer:
The answer would be 40!
Step-by-step explanation:
Estimating ~ rounding
I would round 24% (20%), and 289 (300).
using the formula:
= %/100,
I'm looking for "IS"
I multiply 20 (just 20, no percent) by 200 = 4000.
Then I divide by 100 to get the "IS".
That's how I got my answer!
Hope this helps!
Ok if a student walks 17 meters in 30 seconds he walks 34 meters in a minute 17+17=34 then you take 34(meters in a minute) multiply by 60(minutes in an hour) you get 2040 34x60=2040meters 1609.34 meters equal a mile 2040-1609.34=430.66 meters left theres 1.09361yards in a meter so 430.66x1.09361=470.97yards
so i guess you could say a student would walk 1mile and 470.97 yards if he walked 17 meters in 30 seconds for an hour straight
p.s it made sense in my head
