Answer:
<em>Yellow troop will complete the hike faster than blue troop</em>
<u>Blue troop hikes 1.33 miles in 1 hour</u>
<u>Yellow troop hikes 2.25 miles in 1 hour</u>
Missing portion:
Since the final statement is missing, so we will find how much distance can the troops travels in 1 hour and which troop can complete the hike faster.
Step-by-step explanation:
As given in the statement:
Blue troops travels 
miles ever 
hour:
hr = miles
1 hr = 
1 hr= 
miles = 1.33 miles
Blue troop hikes 1.33 miles in 1 hour
Yellow troops travels 
miles ever 
hour:
hr= miles
1 hr = 
miles
1 hr =
miles =2.25 miles
Yellow troop hikes 2.25 miles in 1 hour
<u><em>Yellow troop will complete the hike faster than blue troop</em></u>
Answer: 11/15
Step-by-step explanation:
Gretchen will earn $48 from mowing in 4 hours
Data
- Amount earned on each lawn = $12
- Number of hours mowing = 4 hours
<h3>What is Rate</h3>
This is the measure of one unit against another unit. An example of this is speed which is the rate of distance covered to time.
In this case, she mows 1 lawn in each hour and earns $12 on each.
To calculate for 4 hours
She earns $48 from mowing 4 lawns

Answer:
An interesting experiment is given. We need to address various questions based on our knowledge of calculus.
Step 2
Part (a)
Time taken for the radius to grow to 2 cm = t1 = r/0.5 = 2/0.5 = 4 hours
Time taken for the radius to become 0 = t2 and the same can be obtained by solving:
r = 2 - √t2 = 0
Hence, t2 = 22 = 4 hours
Hence, the time duration of the entire experiment (from the introduction of the bacteria until its disappearance) = t1 + t2 = 4 + 4 = 8 hours
Step 3
Part (b)
r(t) = 0.5t for 0 ≤ t ≤ 4
and
r(t) = 2 - √(t - 4) for t > 2
Step-by-step explanation:
Speed is the magnitude in a velocity. It is a scalar quantity so it does not have direction unlike velocity which is a vector quantity. Speed and velocity refers to the distance traveled by a moving object per unit of time. We calculate speed as follows:
Speed = distance / time = 84 miles / 2 hours
Speed = 42 miles per hour
