To determine the rate per hour at which the biker traveled, you need to divide the total distance traveled by the total time taken. Here are the steps to calculate the rate:
1. Identify the total distance traveled: The biker traveled 360 kilometers.
2. Identify the total time taken: The journey took 4 hours.
3. Use the formula for rate:
[tex]\[ \text{Rate} = \frac{\text{Distance}}{\text{Time}} \][/tex]
4. Substitute the given values:
[tex]\[ \text{Rate} = \frac{360\ \text{kilometers}}{4\ \text{hours}} \][/tex]
5. Perform the division:
[tex]\[ \text{Rate} = 90\ \text{kilometers per hour} \][/tex]
Thus, the rate at which the biker traveled is 90 kilometers per hour. Therefore, the correct answer is:
90 km/hr
