Question

Blake and Camille both run regularly. Let B(D) be the amount of time, in seconds, that it takes Blake to run D meters. Let C(D) be the amount of time, in seconds, that it takes Camille to run D meters. Assume that B(D) and C(D) are both invertible. For each of the following, give a mathematical expression for the indicted quantity (possibly involving B and/or C): a. The amount of time it takes Camille to run the same distance that Blake runs in 450 seconds is b. The amount of time, in seconds, it takes Blake to run 400 meters is

Chloe and Julia are running partners. In a series of practice runs, they run longer and longer distances without changing pace. They each set up a table to show the ratios of distance to time for their runs: Which statement is true about the ratios shown? Chloe can run 75 meters in the time it takes Julia to run 60 meters. To run 100 meters, it takes Chloe 16 seconds and Julia 25 seconds. To run 300 meters, it takes Chloe 48 seconds and Julia 50 seconds. Chloe can run 50 meters in the time it takes Julia to run 60 meters.

Blake takes part in a 400-m dash where he must run around the end of a track that has a circular arc with a radius of curvature of 60.0 m. Blake starts the race at a constant speed. (a) If he completes the 400-m dash in 47.3 s and maintains constant speed for the entire race, what is his centripetal acceleration as he runs the curved portion of the track? (b) If his acceleration as he runs around the circular end of the track is given by 2.18 m/s2, how long (in seconds) will it take him to complete the 400-m dash? (c) Blake partakes in another race where the track is circular with a circumference of 250 m, find the time needed for him to make one revolution given that he accelerates at 1.89 m/s?

The dog has an owner who throws a tennis ball into the water. When Cooper retrieves the ball, he follows the dotted path. Cooper loves swimming, so he wishes to minimize the time it takes him to retrieve the ball. Cooper wishes to find the ideal place to enter the water, which depends on his speed on land, his swimming speed in the water, and the location of the ball. Cooper has to run 30 yards before entering the water and assuming a speed of 4 yards per second. Under these assumptions, how long will it take him to get to the water? Now let's set this up in general. Let a be the speed at which Cooper runs in yards per second and b be the speed at which he swims in yards per second, where a is a fixed value and b is a fixed value. If Cooper runs a yards and swims b yards per second, where b is the speed at which he swims, we can write an equation based on T, a, b, and the distance to the ball.

00:01 Hi, in this question, koli and julia are doing running practices for longer distances.
00:08 This table shows the ratio of the year runs with respect to distance and time for both koli and julia.
00:17 So, from this table for 300 meter distance, koli takes 48 seconds.
00:39 Whereas julia takes for 300 meter distance 50 seconds...
