Question

question 19 (1 point) how much time does it take a person to walk 12 km north at a velocity of 4 km/hr?
a 6hr
b 3hr
c 2hr
d 4hr

Explanation:

Step1: Recall the formula for time

The formula relating distance (\(d\)), velocity (\(v\)), and time (\(t\)) is \(t=\frac{d}{v}\).

Step2: Substitute the given values

We know that the distance \(d = 12\) km and the velocity \(v = 4\) km/hr. Substituting these values into the formula, we get \(t=\frac{12}{4}\).

Step3: Calculate the result

\(\frac{12}{4}=3\) hours.

Answer:

b. 3hr
