Question

the following table shows the speeds at which jeff does 4 activities. for example, biking has a rate of 19 miles in 2 hours.

activity	miles	hours
walking	14	4
running	15	3
swimming	18	4

which type of activity does jeff do at a speed of 4.5 miles per hour?

choose 1 answer:

a biking

b walking

c running

d swimming

Explanation:

Step1: Recall speed formula

Speed is calculated as $\text{Speed} = \frac{\text{Miles}}{\text{Hours}}$. We need to calculate the speed for each activity using this formula.

Step2: Calculate speed for Biking

For Biking, Miles = 19, Hours = 2. So speed is $\frac{19}{2} = 9.5$ miles per hour.

Step3: Calculate speed for Walking

For Walking, Miles = 14, Hours = 4. So speed is $\frac{14}{4} = 3.5$ miles per hour.

Step4: Calculate speed for Running

For Running, Miles = 15, Hours = 3. So speed is $\frac{15}{3} = 5$ miles per hour.

Step5: Calculate speed for Swimming

For Swimming, Miles = 18, Hours = 4. So speed is $\frac{18}{4} = 4.5$ miles per hour.

Answer:

D. Swimming
