Explanation:
Given
Car drives 215 km east and then 45 km North
Displacement is East direction is
Now, the displacement from that to 45 km North is given by
Net displacement is![\vec{r_2}](/tpl/images/1394/8223/a0e5f.png)
Magnitude of the displacement is
Ответ:
A
Explanation:
Distance (d)=300 miles
Time Taken (t)=6 hours
Here, In 6 hours a train travel distance= 300m
In 1 hours a train travel distance= 300m/6
= 50
Hence, Average Speed is 50 miles per hour.
