The speed you must go to cover a certain distance caries inversely with the time of the trip. Suppose you must travel 54miles per hour to complete your trip 4 hours. How fast must you travel to complete your trip in 3 hours?

What is the least common multiple of 16 and 3?

Ineed in figuring out this problem.

In the figure below, ∠dec ≅ ∠dce, ∠b ≅ ∠f, and segment df is congruent to segment bd. point c is the point of intersection between segment ag and segment bd, while point e is the point of intersection between segment ag and segment df. the figure shows a polygon comprised of three triangles, abc, dec, and gfe. prove δabc ≅ δgfe.
