Time taken by Daniel to catch up with Frank is 4 minutes.
Step-by-step explanation:
The question is on relative speed; speed of a moving object with respect to another.
The two cars are travelling in the same direction at different speeds thus;
Relative speed = speed of Daniel - speed of Frank = 50-45= 5 mph
The time which the two meet = distance/ relative speed
Distance = 1/3 miles, which equals 0.33 miles
Time taken by Daniel to catch up with Frank is = 0.33/5 =0.066 hours = 4 minutes.

Answer:
Step-by-step explanation:
The formula of the directrices are:
A relationship between the hyperbola constants is derived from the absolute value of the slope of the directrix:
The location of the foci indicates that hyperbola is vertical and centered at origin. The distance between foci is equal to . Then, the vertical parameter is:
One of the hyperbola coefficients is determined with the help of the Pythagorean Theorem:
The remaining parameter is found by means of the relationship described previously:
Lastly, the equation of the hyperbola in standard form is:
