That is called square root
Answer:
I am very confused by this
Step-by-step explanation:
so I'ma say yes
In the box where 'Tails' and 'Not six' is, write 68. Then right under that you ADD 50 and 68. Then under 'Six' and 'Tail' you MINUS 79 and 68. And finally under that one you ADD 21 and the answer you got.
So in the end this is how it should look:
Rate = (150 miles)/(3 hrs) = 50 mph
so . . .
(50 mph)*(time) = 400 miles
*divide both sides by 50 mph
time = (400 miles)/(50 mph) = 8 hrs
time = 8 hrs
