The answer is 4.5 hours.
120 miles/2 hours = 60 mph
270-120 = 150 miles
150 miles/60 mph = 2.5 hrs
2 hrs+2.5 hrs = 4.5 hours for the whole trip
Answer:
40mph
Step-by-step explanation:
Using D = rt, the current variables we have are
D = 20 miles
t = 30 minutes
Since the goal is rate, we alter the equation to r = D/t.
In addition, we have to convert minutes into hours so we can
r = (20 / 30)*2/2
r = (40/60)
60 minutes is converted into an hour so the rate <em>r</em> is 40 miles per hour.
r = 40/1
Answer:
0.5
Step-by-step explanation:
The function is represented as y = f(x) =
Now, it is clear from the function given above that, for x = 0, y = f(x) = 10, and for x=1, f(x) = 5, and for x=2, f(x) = 2.5.
Therefore, the value of f(x) is multiplied each time by 0.5 for each unit increase in the value of x.
So, the multiplicative rate of change of the function is 0.5. (Answer)
Answer:
37.5
Step-by-step explanation:
the triangle is enlarged by a factor of 2.5 so you multiply all of the numbers in XYZ by 2.5 then add them
15+10+12.5=37.5 units
