A bee flies 15 miles per hour. Use the formula for distance, rate, and time to answer questions A-C. A. Write the bee's distance
tester [92]

Answer:

Step-by-step explanation:

Speed of the bee = 15 miles per hour.

Formula to represent the speed of the bee will be,

Speed = \frac{\text{distance}}{\text{Time}}

Distance = Speed × Time

Therefore, function representing the distance will be,

F(t) = s × t

Where t = time

s = speed

A). F(t) = 15t

B). If t = 20 minutes ≈ \frac{1}{3} hours

     F(t) = 15t

     F(20) = 15\times \frac{1}{3} = 5 miles

C). If f(t) = 12 miles

     F(t) = 15t

     By substituting these values in the function,

     12 = 15t

     t = \frac{12}{15} = 0.8 hours ≈ 48 minutes
