Question

maria walks 1,500 meters in \\(\frac{1}{4}\\) hour.
what is her speed in kilometers per hour? use 1 kilometer = 1,000 meters.
a. 6 kilometers per hour
b. 6,000 kilometers per hour
c. 375 kilometers per hour
d. 0.375 kilometers per hour

Explanation:

Step1: Convert meters to kilometers

Maria walks 1500 meters. Since 1 kilometer = 1000 meters, we convert meters to kilometers by dividing by 1000. So, \(1500\) meters \(=\frac{1500}{1000}=1.5\) kilometers.

Step2: Find the speed

Speed is calculated by the formula \( \text{Speed}=\frac{\text{Distance}}{\text{Time}} \). The time taken is \(\frac{1}{4}\) hour and the distance (in kilometers) is 1.5 kilometers. To find the speed in kilometers per hour, we need to find out how far she would walk in 1 hour. If she walks 1.5 kilometers in \(\frac{1}{4}\) hour, then in 1 hour (which is 4 times \(\frac{1}{4}\) hour), she would walk \(1.5\div\frac{1}{4}=1.5\times4 = 6\) kilometers per hour.

Answer:

A. 6 kilometers per hour
