Question

myra rode her motorcycle down a straight freeway for a total of 4 hours at a constant velocity. in half of that time, she rode 200 kilometers. what was her velocity? write your answer as a whole number. kilometers per hour down the freeway

Explanation:

Step1: Calculate the time for the first - part

The total time is \(t = 4\) hours. The time for the first - part (when she rode 200 kilometers) is \(t_1=\frac{4}{2}=2\) hours.

Step2: Use the velocity formula

The velocity formula is \(v=\frac{d}{t}\), where \(d = 200\) kilometers and \(t = 2\) hours. So \(v=\frac{200}{2}\).

Answer:

100
