Answer:
1) 2 hours
2) 96 miles
Step-by-step explanation:
1) Eliot and William went hiking. They went at the same speed. Let x mph be their speed.
<u>Elliot:</u>
Distance = 8 miles
Speed = x mph
Time hours
<u>William:</u>
Distance = 12 miles
Speed = x mph
Time hours
It took Eliot less than William, then
So, William's hike was
hours long.
2) <u>Initially:</u>
Distance = 120 miles
Speed = 55 mph
Time hours
<u>Final:</u>
Speed = 44 mph
Time hours
Distance
Using the uniform distribution, we have that:
a) The density curve is given at the end of this question.
b) 16.67% of the time does a customer have to wait between 100 and 120 seconds.
-----------------
The uniform distribution has two bounds, a and b, and the probability of finding a value between c and d is given by:
- Uniform distribution on the interval of 0 to 120 seconds, thus
.
The proportion between 100 and 120 seconds is:
0.1667*100% = 16.67%
16.67% of the time does a customer have to wait between 100 and 120 seconds.
