Question

a car moves 12 km west and then moves 5 km not the total time taken by car is 30 minutes then velocity of car is​

Answer 1

Step-by-step explanation:

velocity = displacement / time

now, displacement = √ 12^2 +5^2

d= √169

d= 13km

d = 13000 m

time = 30 min

t = 1800 sec

Now, v = 1300/ 1800

v= 13/ 18 m/s

OR

v = 13/ 30 km/ min
