mark for review (will be highlighted on the review page)

Explanation:

Step1: Recall the formula for average speed

The formula for average speed is \( \text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}} \).

Step2: Identify the given values

The total distance between Boston and Hartford is 240 kilometers, and the total time taken is 4 hours.

Step3: Substitute the values into the formula

Substitute the distance (\( d = 240 \) km) and time (\( t = 4 \) hours) into the formula:
\( \text{Average Speed} = \frac{240}{4} \)

Step4: Calculate the result

\( \frac{240}{4} = 60 \) km/hour.

Answer:

B. 60 km/hour
