Answer:
The last part.
Step-by-step explanation:
The error is only at the last part. Basically the answer part.
The answer should be —
We don't multiply the square roots when adding or subtracting. That'd contradict the rules.
Here, we let the square root of five as x-term.
As we add up, we would get 13x. Thrn we convert x-term back to square root of five.
The answer would be —
Remember that we don't multiply the square roots when adding or subtracting.
Radical 7
radical 84=2 radical 21
radical 21 divided by 2 radical 3 is radical 7
You need to use the steps of a^2+b^2=c^2
A and B are the legs. C is the hypotenuse.
If we follow that through, we find the answer is 20.
3 1/2 miles = 7/2 miles
1/2 hours= 30 minutes
So,
In 30 mins, travelled 7/2 miles
In 1 min, travelled 7/2 ÷ 30= 7/2× 1/30 = (7×1)/(2×30) = 7/60 miles
In 60 mins, travelled (7×60)/60 miles = 420/60 miles = 7 miles.
Hence, the speed is 7 miles per hour.
I hope this is what you mean, sorry if it is not
