A skydiver falls 144 feet at 3 seconds. What is the unit rate?

Question

48 feet per second

Write as #144/3# but for unit rate we need #?/1# So we need to change the 3 into 1. We can do this by dividing it by 3. Using the rule: "what you do to the bottom you also do to the top" (this does not work for add or subtract). Divide the top and bottom by 3 #144/3" "->" "(144-:3)/(3-:3) " "->" "48/1# So feet per second #" "->" "("feet")/("seconds")" "->" "48" feet per second"#

undefined The unit rate of the skydiver's fall can be calculated by dividing the distance fallen by the time it took to fall that distance.

Unit rate $= \frac{\text{Distance fallen}}{\text{Time taken}}$

Given:
Distance fallen = 144 feet
Time taken = 3 seconds

Unit rate $= \frac{144 \text{ feet}}{3 \text{ seconds}}$

$$= 48 \text{ feet/second}$$

So, the unit rate of the skydiver's fall is 48 feet per second.

undefined The unit rate for the skydiver's fall can be calculated by dividing the total distance fallen by the time taken. In this case, the skydiver fell 144 feet in 3 seconds.

To find the unit rate, we divide the distance fallen by the time taken:

Unit rate = Distance fallen / Time taken

Unit rate = 144 feet / 3 seconds

Unit rate = 48 feet/second
