Answer:6km
Step-by-step explanation:
Given
when Alice finishes the race Becky is 8km From finishing line
and caitlin 12 km from finishing line.
Suppose t is the time require by Alice to finish the race
and
be the velocity of alice ,becky and caitlin
thus 
thus 
say t' is time required by beckey to complete 8 km thus
therefore for Caitlin
Thus caitlin will cover a distance of 6 km in t' time and 6 km away from finishing.
-244 this it’s the answer because you have to simplify on both sides and then add them together to get your answer
Answer:
The time the object takes to fall on the ground from 224 feet is 3.74 s.
Step-by-step explanation:
In this case we have a known quantity, the distance of the fall that is 224 feet and a equation that represents the motion of this fall that is d = 16t^2. We wish to find the time it'll take this object to fall, so we can solve this equation for t. It goes as follows:
d = 16t^2
d/16 = t^2
t^2 = d/16
t = \sqrt(d/16)
t = [\sqrt(d)]/4 = [\sqrt(224)]/4 = 14.97/4 = 3.74 s
where \sqrt is the square root of the number.
