Question

A man walks for 2 hours at a speed of 3m/s. How far does he travel?

Answer 1

First you get the data:

• Velocity (v) = 3m/s
• Distance (d) = ??
• Time (t) = 2hr

Time conversion: hours to seconds:

• 1 hour = 3600 seconds

$\bf{2\not{h}*\left(\dfrac{3600 \ seg}{1\not{h}}\right)=7200 \ seg }$

We calculate the distance, using the formula:

                           $\bf{d=t*v }$

                           $\bf{d=3600\not{seg}*3\frac{m}{\not{m}} }$

                           $\bf{d=21600 \ m}$

Answer: I travel to 21600 meters.
