Acar passes a landmark on a highway traveling at a constant rate of 50 kilometers per hour. one hour later, a second car passes the same landmark traveling in the same direction at 70 kilometers per hour. how much time after the second car passes the landmark will it overtake the first car?

Let t = time for the 2nd car to catch the 1st one

From the problem we know car 1 is 5o km ahead of 2nd

70t=50t+50

70t-50t=50

20t=50

T = 50/20 = 2.5

They will be together after 2.5 hours, 2 hours and 30 minutes

answer with step-by-step explanation:

a. ∠j is supplementary to ∠k - true:

(opposite angles of a trapezoid are supplementary which means that they add up to 180 degrees)

b. kl is parallel to jm - true:

(opposite sides are parallel to each other in a trapezoid)

c. jk is perpendicular to kl - false:

(clearly, jk does not make a right angle with kl)

d. jk is parallel to lm - false:

(jk and lm are two lines opposite in direction to each other so they cannot be parallel)

e. ∠j is congruent to ∠m - true:

(the angles on each side of the base are congruent)

f. ∠j is congruent to ∠k - false:

(the angles on the same side but opposite side of the base are not congruent)
