Question

calculate the velocity of a car that travels 556 kilometers northeast in 3.4 hours.

Explanation:

Step1: Recall the formula for velocity

Velocity \( v \) is defined as the displacement \( d \) divided by the time \( t \), so \( v=\frac{d}{t} \).

Step2: Identify the given values

The displacement \( d = 556 \) kilometers (northeast) and the time \( t = 3.4 \) hours.

Step3: Calculate the velocity

Substitute the values into the formula: \( v=\frac{556}{3.4}\). Calculating this, \( \frac{556}{3.4}=163.52 \) (approximately). Since velocity includes direction (northeast), the velocity is \( 163.52 \) km/hr northeast.

Answer:

163.52 km/hr northeast
