Answer:
Step-.by-step explanation:
To determine The probability of both of these occurring, you would multiply the probability of each together. So, there is a 1/7 chance of the first salesman getting the right key, and 1/6 chance of the second salesman getting the right key. 1/7 x 1/6= 1/42 chance of both occurring.
Answer:
It will take 4.71 hours to travel a distance of 221.43 miles
Step-by-step explanation:
Given
Distance covered in time 7.99 hours is 375.32 miles.
Now we know that speed is equal to distance per unit time.
Therefore,
![speed = \frac{distance}{time} \\= \frac{375.32}{7.99}\\=46.97\ mi/h](https://tex.z-dn.net/?f=speed%20%3D%20%5Cfrac%7Bdistance%7D%7Btime%7D%20%5C%5C%3D%20%5Cfrac%7B375.32%7D%7B7.99%7D%5C%5C%3D46.97%5C%20mi%2Fh)
Which is the constant speed, hence now time taken for a distance of 221.43 miles will be
![time = \frac{distance}{speed} \\=\frac{221.43}{46.97} \\=4.71\ h](https://tex.z-dn.net/?f=time%20%3D%20%5Cfrac%7Bdistance%7D%7Bspeed%7D%20%5C%5C%3D%5Cfrac%7B221.43%7D%7B46.97%7D%20%5C%5C%3D4.71%5C%20h)
Therefore, the time taken to cover 221.43 miles is 4.71 hours.
Answer:
