Answer:
The magnitude of the magnetic field is 7.49x10⁻⁶T
Explanation:
The magnetic field is:

Where
i = current = 3 A
R = radius = 2.4 cm = 0.024 m
r = distance = 0.72 cm = 7.2x10⁻³m
Replacing:

8.33 m/s
Explain:
If you understand what 1 km = 1000 m and 1 hr = 60*60 seconds signify, you already know what they mean. If you translate 1000 m/ 3600 s to km/hr, you'll get 5 m/ 18 s, which you can multiply by 30 to get (30 x 5)/18 = 8.33 m/s.
