Question

if the person walked at a constant speed, what is the estimated value of the missing data? a. 25 m b. 50 m c. 75 m d. 100 m

Explanation:

Step1: Calculate the speed

Since speed \(v=\frac{\text{distance}(d)}{\text{time}(t)}\), using the data \(d = 150m\) and \(t=2.0min\), we have \(v=\frac{150}{2}=75m/min\).

Step2: Find the missing distance

For \(t = 1.0min\) and \(v = 75m/min\), using the formula \(d=v\times t\), we get \(d=75\times1 = 75m\).

Answer:

C. \(75m\)
