Answer:
The number of miles/the number of hours
Step-by-step explanation:
If the number of hours is not equal to 1, multiply the numerator and denominator by the inverse of the number of hours.
For example, 10 (miles)/2 (hours)
The inverse of 2 is 1/2, so --> the new equation is 10/2 * 1/2 / 1/2 or
10* 1/2 and 2 * 1/2
When multiplied out, this leads to 5/1 or 5 miles per hour

Answer:
8.5 inches
Step-by-step explanation:
First let's find the time t when the depth of the snow is 7 inches.
To do this, we just need to use the value of D = 7 then find the value of t:
We want to find the depth of snow one hour from now, so we just need to use the value of t = 3 to calculate D:
The depth of snow one hour from now will be 8.5 inches.
Answer:
90
Step-by-step explanation:
4/15 which is our fraction distance/time
our other fraction is 24/x (x is our variable to find our time)
Now we are doing the buultterfly method
set it up
now multiply 4*x= 4x
15*24=360
now divide 4x ÷ 4 to get our variable alone
do the same to the other side
4 ÷ 360= 90
so x= 90 which is our missing number
