1. a plane left greenville at 1:00pm in route to las vegas. las vegas is 1000 miles from greenville. if a plane is traveling 200 mph and it has been flying for 4 hrs, how many miles are left before the plane reaches las vegas?
2. what is the speed of a car if it travels 100 miles in 2 hours? how do you make this speed a velocity?

Explanation:

Question 4

Step1: Calculate the distance covered

Use the formula \(d = vt\), where \(v = 200\) mph and \(t=4\) hrs.
\(d=200\times4 = 800\) miles

Step2: Calculate the remaining distance

The total distance \(D = 1000\) miles. Remaining distance \(d_{remaining}=D - d\)
\(d_{remaining}=1000 - 800=200\) miles

Step1: Calculate the speed

Use the formula \(s=\frac{d}{t}\), where \(d = 100\) miles and \(t = 2\) hours
\(s=\frac{100}{2}=50\) mph

Step2: Convert speed to velocity

Velocity is speed with direction. So, if we specify the direction (e.g., north - east) in which the car is moving, the speed (50 mph) becomes a velocity (50 mph in a particular direction)

Answer:

200 miles
