From an elevation of 0.5 m below the surface of the water, a swimmer dives at a rate of 0.25 m/s. What is the depth of the swimmer after 4 minutes?
From an elevation of 0.5 m below the surface of the water, a swimmer dives at a rate of 0.25 m/s. What is the function rule for the swimmer's depth, d, and time, t?
.5 + .25(4*60) = final depth
4 * 60 = time in seconds
To find the depth of the swimmer after 4 minutes, we need to calculate the distance the swimmer has traveled while diving at a rate of 0.25 m/s over a period of 4 minutes.
First, we need to convert 4 minutes to seconds. Since there are 60 seconds in 1 minute, 4 minutes is equal to 4 x 60 = 240 seconds.
Now we can calculate the distance using the formula: distance = rate x time.
Given that the rate is 0.25 m/s and the time is 240 seconds, we have:
distance = 0.25 m/s x 240 s = 60 meters.
Therefore, after 4 minutes of diving at a rate of 0.25 m/s, the swimmer will be at a depth of 60 meters below the surface of the water.
