Question

isaiah runs for exercise. he runs 6.2 km in 20 min. calculate his average speed. 0.3 km/min 0.8 km/min 1.5 km/min 3.2 km/min

Explanation:

Step1: Recall the formula for average speed

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

Step2: Substitute the given values into the formula

Given \(d = 6.2\) km and \(t=20\) min. Then \(v=\frac{6.2}{20}\).

Step3: Calculate the value

\(\frac{6.2}{20}=0.31\approx0.3\) (rounded to one - decimal place).

Answer:

0.3 km/min
