Answer:
3890000000
Step-by-step explanation:
5 m/sec or 300m / min
using speed = 
change 5 min 20 sec to seconds = (5 × 60) + 20 = 320 sec
speed = 
= 5m / second or
speed = 60 × 5 = 300m / minute
Answer:
The two numbers are:
30 and 18
Step-by-step explanation:
a + b = 48
a - b = 12
From the first eq.
a = 48 - b
Replacing this last value in the second eq.
(48 - b) - b = 12
48 - 2b = 12
48 - 12 = 2b
36 = 2b
36/2 = b
18 = b
from the first eq.
a + 18 = 48
a = 48 - 18
a = 30
Check:
from the second eq.
a - b = 12
30 - 18 = 12
