To solve the problem of finding the mountain hiker's ascent rate in kilometers per hour, we will use the formula for rate, which is given by:
\[ \text{Rate} = \frac{\text{Distance}}{\text{Time}} \]
In this case, the distance ascended is \( \frac{3}{4} \) kilometers, and the time taken is \( \frac{1}{16} \) of an hour.
Step 1: Finding the ascent rate
-
Set up the equation:
\[ \text{Rate} = \frac{\frac{3}{4} \text{ km}}{\frac{1}{16} \text{ hr}} \]
-
Dividing fractions (which is the same as multiplying by the reciprocal):
\[ \text{Rate} = \frac{3}{4} \div \frac{1}{16} = \frac{3}{4} \times \frac{16}{1} \]
So, the answer corresponds to the operation \( \frac{3}{4} \div \frac{1}{16} \).
Response to Question 1:
The correct response is: 34÷116 \( \frac{3}{4} \div \frac{1}{16} \)
Step 2: Calculating the rate
Now, we can calculate the rate:
\[ \frac{3}{4} \times 16 = \frac{3 \times 16}{4} = \frac{48}{4} = 12 \]
Thus, the ascent rate is \( 12 \) kilometers per hour.
Response to Question 2:
The mountain hiker's ascent rate is: 12 kilometers per hour.
