Question

tina drove from orlando to cleveland. the trip took her (16.5\text{ hr}) to drive. her trip odometer read (1,095\text{ mi}) when she reached cleveland.

which of the following represents tinas approximate constant speed for the trip?

a. (61\text{ mph})

b. (70\text{ mph})

c. (66\text{ mph})

d. (68\text{ mph})

Explanation:

⚡ Using what you learned: Unit Rate

Step 1: Identify given values

$$ \text{Distance} = 1,095\text{ mi} $$

$$ \text{Time} = 16.5\text{ hr} $$

Step 2: Calculate constant speed

$$ \text{Speed} = \frac{\text{Distance}}{\text{Time}} $$

$$ \text{Speed} = \frac{1,095\text{ mi}}{16.5\text{ hr}} \approx 66.36\text{ mph} $$

Step 3: Compare with options

The closest value to \( 66.36\text{ mph} \) is \( 66\text{ mph} \).

Answer:

C. 66 mph
