A cyclist travels a distance of 837 1/2 feet in 25 seconds. The cyclist travels at a constant rate. What is the unit rate, in fe

wel

Answer:

$\boxed{33.5 \ \text{feet/second}}$

Step-by-step explanation:

To find the unit rate, we need to find out how much distance does the cyclist travel in 1 second. For that, we need to use the unitary method. A unitary method is a method that determines the unit rate of an object.

Note: Since the cyclist travels at a constant rate, unitary method can be used.

$\rightarrow 837 \dfrac{1}{2} \ \text{feet in 25 seconds}$

$\rightarrow 837.5 \ \text{feet} = 25 \ \text{seconds}$

Divide both sides by 25:

$\rightarrow \dfrac{837.5}{25} \ \text{feet} = \dfrac{25}{25} \ \text{seconds}$

$\rightarrow 33.5 \ \text{feet} = 1 \ \text{seconds}$

$\rightarrow \boxed{33.5 \ \text{feet/second}}$

Find the percent of change. Round to the nearest tenth of a percent if necessary.

Rom4ik [11]

9514 1404 393

Answer:

100%

Step-by-step explanation:

The percentage change can be computed from ...

pct change = ((new value)/(old value) -1) × 100%

= ((1/2)/(1/4) -1) × 100%

= (2 -1) × 100%

= 100%

The increase by 1/4 from 1/4 to 1/2 is an increase of 100%.
