Answer:
Tim needs to finish 59/90
Step-by-step explanation:
Add together what Evan Claire and Jaya ran  
9/10 + 7/9+ 2/3
The common denominator is 90
9/10 (9/9) +7/9 *10/10  + 2/3 *30/30
81/90 + 70/90 + 60/90
211/90
We need 3 km = 3 *90/90 = 270 /90
270/90 - 211/90 = 59/90

= sqrt (16 + 9)
= 5 units answer
