Ranjana has average velocity 3.2 m/s
How long does she take to cover a displacement
of 256 m

t= 80 seonds

Explanation:

Given that,

The average velocity of Ranjana, v = 3.2 m/s

We need to find how long does she take to cover a displacement  of 256 m. Let she takes t time.

We know that,

Average speed = distance/time

So,

So, she will take 80 seconds to cover a displacement of 256 m.

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

the total distance traveled by the car is

30km + 49km = 79 km .
