Answer: 47°C
Step-by-step explanation:
Since we are given the velocity, all we have to do is plug in 358 for v and solve for t.
[divide both sides by 20]
[square both sides to cancel out square root]
[subtract both sides by 273]
Now that we know the temperature is 47.41°C, we know our answer choice is D.
Answer:
Rabbit is faster than bear.
Step-by-step explanation:
Speed of rabbit or bear is determined by their rate of change of their distances with time.
The distance covered by rabbit in hours is given as:
The above equation is of the form , where,
is the rate of change of
with
.
Therefore, the rate of change of rabbit's distance with time is 30 mi/h.
Now, from the graph, the slope is given as the rise over run.
Rise is 50 miles and run is 2 miles.
So, rate of change of bear's distance with time is,
Now, 30 is greater than 25. So, rabbit is faster than bear.
