Question

four students ran a race at school and calculated their speeds. their results are shown in the table. what was the speed of the fastest student? enter the correct answer in the box. m/s

Explanation:

Step1: Recall the speed formula

The formula for speed is \(v=\frac{d}{t}\), where \(v\) is speed, \(d\) is distance, and \(t\) is time.

Step2: Calculate the speed for each student

• Student 1: \(v_1=\frac{100}{10}=10\space m/s\)
• Student 2: \(v_2=\frac{100}{15}=\frac{20}{3}\approx6.67\space m/s\)
• Student 3: \(v_3=\frac{100}{5}=20\space m/s\)
• Student 4: \(v_4=\frac{100}{20}=5\space m/s\)

Answer:

\(20\)
