Answer:
Troy = 5/7 km = (5 x 3)/(7 x 3) = 15/21 km
Tim = 2/3 km = (2 x 7)/(3 x 7) = 14/21 km
Comparing 15/21 and 14/21
15/21 > 14/21
=> Troy covered a longer distance
Find the difference:
Difference = 15/21 - 14/21 = 1/21
=> Troy covered 1/21 km longer
Answer: Troy covered a longer distance. He covered 1/21 km longer.
