Question

show instructions question 5 (1 point) a car traveled 1425 km from el paso, tx to dallas, tx in 12.5 hours. what was the car’s average speed? a 80 km/h b 114 km/h c 90 km/h d 106.7 km/h

Explanation:

Step1: Recall the formula for average speed

The formula for average speed \( v \) is \( v=\frac{d}{t} \), where \( d \) is the distance traveled and \( t \) is the time taken.

Step2: Identify the given values

We are given that the distance \( d = 1425\space km \) and the time \( t=12.5\space hours \).

Step3: Substitute the values into the formula

Substitute \( d = 1425 \) and \( t = 12.5 \) into the formula \( v=\frac{d}{t} \). So we have \( v=\frac{1425}{12.5} \).

Step4: Calculate the value

\( \frac{1425}{12.5}=114 \space km/h \) (by performing the division: \( 1425\div12.5 = 114 \)).

Answer:

b. 114 km/hr
