Answer:
- Distance in 47 minutes = 0.75 × 47 = 35.25 miles
- Distance in 1 hour or (60 minutes) = 0.75 × 60 = 45 miles
Step-by-step explanation:
Given that the car is traveling at a steady speed.
Distance traveled in 2 1/3 or 7/3 or (2.33) minutes = 1 3/4 miles
= 7/4 or 1.75 miles
Thus,
distance in 1 minute: 1.75/2.33 = 0.75 miles per minute
Thus,
- Distance in 47 minutes = 0.75 × 47 = 35.25 miles
- Distance in 1 hour or (60 minutes) = 0.75 × 60 = 45 miles
Answer:

And using the cdf we got:

Step-by-step explanation:
Previous concepts
The exponential distribution is "the probability distribution of the time between events in a Poisson process (a process in which events occur continuously and independently at a constant average rate). It is a particular case of the gamma distribution". The probability density function is given by:

And 0 for other case. Let X the random variable that represent the random variable of interest and we know that the distribution is given by:

We know the variance on this case given by :

So then the deviation is given by:

And if we solve for
we got:

The cumulative distribution function for the exponential distribution is given by:

Solution to the problem
And for this case we want to find this probability:

And using the cdf we got:
