Answer:
Step-by-step explanation:
Bob ran the first part of a 12 km race at a speed of 8 kmph. He ran the second part of the
race at 10 kmph. If his total time for the entire race was 1.74 hours, how far did he run in
the first part of the race?
First part :
Total Distance = 12 km
First part Speed = 8kmph
Let distance covered on first part = x
Second part speed = 10kmhr
(8*x)
Hey there ..
Contacted you through the comments asking for the formulas but you seem like forgot to put em ..
Will be pleased to help anytime ..
See ya
Points (-1,4) (3,6)
Slope: (6-4)/(3+1) = 2/4
The slope is 1/2
PERIMETER = 2 (LENGTH + WIDTH)
PERIMETER = 2 LENGTH + 2 WIDTH
Given: Length 5 inches
P = 2(5 in) + 2w
P = 10 in + 2w
Perimeter is dependent in both length and width. Changes in any length of width will automatically change perimeter.
For find width using the perimeter formula:
P = 10 + 2w
P - 10 = 2w
(P-10)/2 = w
P/2 - 5 = w
w = P/2 - 5
If the perimeter and length is given, you can use the derived formula to solve for width.
Then they all will equal the same thing when you divide them.
Example: A = 5 B = 20 20 divided by 5 = 4
C = 28 D = 7 28 divided by 7 = 4
