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.
Answer: 5
Step-by-step explanation:
1. You have the following expression given in the problem above:

2. You can estimate the result by rounding the numerator and the denominator.
3. As you can see, you can round up 97.5 to 100.
4. Then, you can round up 1.96 to 2.
5. Therefore, you have:

6. Therefore, the result is 5.
Answer:
x ≤ 13.2.
Step-by-step explanation:
6 ≥ x/2.2
Multiply both sides by 2.2:
6 * 2.2 ≥ x
x ≤ 13.2.
