Answer:
The easiest approach is to realise that one hour is 3 times longer than 20 minutes. The longer the time, the more they will pave.
215 of a mile, in 20 minutes, how much in 60 minutes?#
They will pave 3 times more.
215×31=615 of a mile
615=25 of a mile
You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by 20) and them multiply by 60 to find how much in one hour.
Look at what happens:
215÷20×60
=215×120×603
=215×3 ← exactly the same maths.
=25
X=h/4+5/4 is the correct answer
5 10 15 20 25 30 35 40 45 50 55 60 64 70 75 80 85 90 95 100, 105 110 115 120 125 130 (135) 150 155 160 165 170 (175)
Five multiplied each number.

Answer:
x = 14.5
can also be written as;
x = 29/2
Step-by-step explanation:
Real numbers can be both rational and irrational.
sqrt(13) = 3.60555
sqrt(14) = 3.74166
If you're looking for a rational number, there are lots of them to choose from. Easiest is probably 3.7 = 37/10.
An irrational number in this range might be sqrt(27/2).
Hope this helps!
