A runner starts $178 \mathrm{~m}$ West of a flagpole and runs East at $8.1 \mathrm{~m} / \mathrm{s}$. How long (in seconds) does it take the runner to reach the flagpole?
QUESTION 7
Answer
Final Answer: It takes the runner approximately \(\boxed{21.98}\) seconds to reach the flagpole.
Step 1 ：A runner starts 178 m West of a flagpole and runs East at 8.1 m/s. We need to find out how long (in seconds) it takes the runner to reach the flagpole.
Step 2 ：We can use the formula for time which is distance divided by speed.
Step 3 ：Substitute the given values into the formula: time = \(\frac{distance}{speed}\) = \(\frac{178}{8.1}\)
Step 4 ：Calculate the time: time = 21.97530864197531
Step 5 ：Round the time to two decimal places: time = 21.98
Step 6 ：Final Answer: It takes the runner approximately \(\boxed{21.98}\) seconds to reach the flagpole.
