In the first 5 seconds, a body travelled 10 meters. In the first 10 seconds of the travel, the body travelled a total of 30 meters, which means that in the last 5 seconds, it travelled 20 meters (30m + 10m). The relation of speed (v), distance (d), and time (t) can be expressed as: v = d/t
We need to calculate the speed of the second 5 seconds of the travel: d = 20 m (total 30 meters - first 10 meters) t = 5 s (time from t = 5 seconds to t = 10 seconds)
<span><span>A body travels 10 meters during the first 5 seconds of its travel,and a total of 30 meters over the first 10 seconds of its travel
20miles / 5sec = 4miles /sec would be the average speed for the last 20 min</span><span> </span></span>
