A car travels northwest for 2 hours and covers a distance of 90 miles. What is the average velocity of the car? a 40mi/h northwest b 45mi/h northwest 42mi/h northwest d 36mi/h northwest

## Step 1<br />The problem involves calculating the average velocity of a car. The formula for average velocity is given by:<br />### **Average Velocity = Total Distance / Total Time**<br />## Step 2<br />In this problem, the total distance covered by the car is 90 miles and the total time taken is 2 hours.<br />## Step 3<br />Substitute the given values into the formula:<br />### **Average Velocity = 90 miles / 2 hours**<br />## Step 4<br />Calculate the average velocity:<br />### **Average Velocity = 45 miles/hour**<br />## Step 5<br />The direction of the velocity is given as northwest.
