Darla and dave leave school each day at 2: 00 p. m. on their bikes and travel in opposite directions. if darla rides at a constant rate of 12 kilometers per hour and dave rides at a constant rate of 14 kilometers per hour, after how many hours are they 65 kilometers apart?

a 1.25
b. 2.5
c. 5
d. 6.5

2.5 hours

Step-by-step explanation:

12 + 14 = 26

65 / 26 = 2.5

Hope this helps you! :)

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

$4034.40

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
