Answer:
14 yards
Step-by-step explanation:
Let distance covered by Jack be X yards.
given Anna finished a race five yards ahead of jack
therefore Anna covered 5 yards more than Jack .
Hence if jack covered X yards, then Anna covered X + 5 yards.
other condition
jack finished nine yards ahead of tina
It suggest that Jack covered 9 yards more than Tina. It can be also said that Tina covered 9 yards less than Jack.
if Jack covered X yards, then Tina covered X - 9 yards
Now
Distance covered by Anna = X + 5 yards
Distance covered by Tina = X - 9 yards
It can be seen that Anna covered more distance than Tina as X + 5 is greater tha X - 9
Difference in distance covered by Tina and anna is
= Distance covered by Anna - Distance covered by Tina
= X + 5 yards - ( X - 9) yards
= X + 5 - X + 9 yards
= 14 yards
Therefore Anna was 14 yards ahead of Tina.
