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.

\\(\circ\\) a. 6 kilometers per hour
\\(\circ\\) b. 375 kilometers per hour
\\(\circ\\) c. 0.375 kilometers per hour
\\(\circ\\) d. 6,000 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, \( 1500 \text{ meters} = \frac{1500}{1000} = 1.5 \text{ kilometers} \).

Step2: Find the speed

Speed is calculated by distance divided by time. The time is \( \frac{1}{4} \) hour. So, speed \( = \frac{\text{distance}}{\text{time}} = \frac{1.5}{\frac{1}{4}} \). Dividing by a fraction is the same as multiplying by its reciprocal, so \( \frac{1.5}{\frac{1}{4}} = 1.5 \times 4 = 6 \) kilometers per hour.

Answer:

A. 6 kilometers per hour
