Answer:
Part A: Kimberly
Part B:
Becca = 22.5 miles, Kimberly = 25 miles
Step-by-step explanation:
Part A:
Given that Becca runs at a constant speed of 4.5 miles per hour, use the table to find the constant speed that Kimberly runs, and compare who runs faster.
Let x = time
y = distance
k = speed = y/x
Equation for each person can be written as: y = kx
Therefore:
✔️Equation for Becca if k = 4.5
y = 4.5x
✔️Find k (speed) of Kimberly using (2, 10):
Speed (k) = y/x
k = 10/2
k = 5 miles per hour
Equation for Kimberly would be:
y = 5x
Comparing their speed, Kimberly runs faster because she covers more miles per hour than Becca does.
Part B:
For Becca, substitute x = 5 into Becca's equation, y = 4.5x
Thus:
y = 4.5*5 = 22.5 miles
For Kimberly, substitute x = 5 into Kimberly's equation, y = 5x
Thus:
y = 5*5 = 25 miles
17/10
or 1 7/10
i did it on my calculator lol
80 = 5 x 4 x 4
they have 4 flavors of icecream
you get this by multiplying all the variables and how many different possibilities each variable can be
so,
5 different syrups (5)
4 different candy toppings (4)
from that you know 5 x 4 x ? = 80
so 5 x 4 = 20, and 20 x 4 = 80
so 4 different flavors of ice cream (4)
Answer:
31.25 minutes
Step-by-step explanation:
12.5 minutes divided by 2 (miles) = 1 mile per 6.25 minutes
6.25 x 5 = 31.25
<em>9/20+5/12=14/32/2 equals a over all 7/16</em>
