Answer:
In traffic, she drove for 3 hours
and After the traffic cleared she drove for 2 hours.
Explanation:
Given that the road trip was 136 miles;

The first part of the trip there was lots of traffic, she only averaged 16 mph;

The second part of the trip there was no traffic so she could drive 44 mph;

She traveled for a total of 5 hours;

let x represent the time in traffic when she traveled at 16 mph

the time the traffic is clear would be;

Recall that distance equals speed multiply by time;

substituting the values;

solving for x;

So;

Therefore, In traffic, she drove for 3 hours
and After the traffic cleared she drove for 2 hours.
(x+7)(x+3) so therefore you set each equation = 0...
x + 7 = 0
x + 3= 0
and solve
x = -3
x = -7
X = multiplication
h = height
r^2 = radius squared
Formula of a cylinder: Pi x r^2 x height
So, if 176 = 3.14... times 4^2 times h
Then, 176 = 3.14 times 16h
Next, 176 = 50.24h
Finally, 3.5 = h
You can then check your work by plugging 3.5 back in for the missing height and round to the nearest tenth. :) The answer should come out the same if done correctly.
Answer:33
Step-by-step explanation:
3850/(155-45)
=3850/115
=33.4
Round up to 33.
