Answer:
current speed = 12 mph
Step-by-step explanation:
distance / rate = time
time upstream + time downstream = 26
25 / (13-c) + 25 / (13+c) = 26 ( c = current speed)
solve for c = 12 mi/hr
Its identity property of division I’m pretty sure
2.5(5)= 12.5
12.5+ 50= 62.5
Therefore, the eucalyptus tree will be 62.5 cm in 5 days.
Hope this helps!
