Answer:
Dennis skated 35/4 of track in two minutes.
35/4 = 8 3/4
Explanation:
Given that;
Daniel skated 2 1/2 of the way around the track in two minutes
Daniel = 2 1/2 = 5/2 of track
her younger brother skated 3 1/2 of Daniels distance in two minutes
Dennis = 3 1/2 of Daniel's = 3 1/2 of 5/2
Dennis = 3 1/2 × 5/2 = 7/2 × 5/2
Dennis = 35/4 = 8 3/4
Therefore, Dennis skated 35/4 of track in two minutes.
