Question

1. the ramirez family is taking a trip to the coast. they live 270 miles from the coast and want to make the trip in 4.5 hours. what average speed do they need to drive? a. 50 mph b. 60 mph c. 65 mph d. 70 mph

Explanation:

Step1: Recall the speed formula

The formula for speed is \( \text{Speed} = \frac{\text{Distance}}{\text{Time}} \). Here, the distance is 270 miles and the time is 4.5 hours.

Step2: Substitute values into the formula

Substitute distance \( d = 270 \) miles and time \( t = 4.5 \) hours into the formula: \( \text{Speed} = \frac{270}{4.5} \).

Step3: Calculate the speed

Calculate \( \frac{270}{4.5} \). We can rewrite 4.5 as \( \frac{9}{2} \), so \( \frac{270}{\frac{9}{2}}=270\times\frac{2}{9} = 60 \) mph.

Answer:

B. 60 mph
