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. -0.3 > -0.33

7,24

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
