----------- or -----------
2 sqrt(3) 2
Step-by-step explanation:
3 sqrt(8)
-----------------
4 sqrt(6)
3 sqrt(4*2)
-----------------
4 sqrt(3*2)
We know that sqrt(ab) = sqrt(a) sqrt(b)
3 sqrt(4) sqrt(2)
------------------------
4 sqrt(3) sqrt(2)
Canceling the sqrt(2) and sqrt(4) is 2
3*2
----------
4 sqrt(3)
3
-----------
2 sqrt(3)
We can simplify the answer be multiplying by sqrt(3)/sqrt(3)
3 sqrt(3)
----------- * ----------
2 sqrt(3) sqrt(3)
3 sqrt(3)

Answer:
0.83 mi/min
Step-by-step explanation:
Start with 80 km/hr. Convert this to the units miles/hr:
(80 km/hr)(1 mile/1.6 km) = 50 miles/hr
Next, apply the equality 60 min / 1 hr = 1 to 50 miles/hr:
50 miles. 1 hr
------------- * ------------ = 5/6 mi/min, or 0.83 mi/min
hr 60 min
