a bullet fired from a gun traveled 3,600 m south in 6.0 seconds. What was its velocity in (a) m/sec and (b) km/hour?​
SSSSS [86.1K]

Step-by-step explanation:

Velocity = Displacement/Time

a) Velocity in m/s = 3600m/6s

= 600m/s

b) (Converting m into km)

1000m = 1km

3600m = ?

3600/1000 = 3.6km

(Converting secs to hours)

1mins = 60secs

60mins = ?

60 * 60 = 3600 secs

This means there are 3600 secs in 1 hour

3600secs = 1hour

6.0 secs = ?

6.0/3600 = 0.00167 hours (approximately)

Velocity in km/h = 3.6km/0.00167h

= 2155.69km/h (approximately)

In summary...

a) 600m/s

b) 2155.69km/h

Which would feed more people 4/6 of a grape or 3/6 of a watermelon
Westkost [7]
Hello Almighty11,
Picture a grape and almost all of it, thats how much 4/6 of a grape would be.

3/6 of a watermelon is half of a whole watermelon, so it would definitely be the 3/6 watermelon.
