Answer:
It would approximately be 3.73 m/h
Step-by-step explanation:
0.8 mins is 48 seconds
I then divided 8000 by 48 seconds to see how many cm it traveled per second.
It traveled 166.666666667 cm per second
I then converted cm to feet
so it was 5.468066491699474 feet per second
I then converted feet to miles, so it was 0.0010356186537309611598 miles per second.
Then I multiplied it by 60 so it was 0.06213711922 miles per minute.
Finally I multiplied it by 60 again to make it 3.72822715343 miles per hour.
I rounded it to the nearest hundredth making it 3.73 m/h

Answer : The two correct options are,
3.4a + 5.6b
5.6b + 3.4a
Step-by-step explanation :
The given expression is:
(-2.4a - 1.8b) - (-3.8a - 4.4b) + (2.0a + 3.0b)
First we have to open the brackets.
⇒ -2.4a - 1.8b + 3.8a + 4.4b +2.0a + 3.0b
Now keep like terms together.
⇒ -2.4a + 3.8a +2.0a + 3.0b - 1.8b + 4.4b
By subtraction or addition, we get:
⇒ 3.4a + 5.6b
or,
⇒ 5.6b + 3.4a
Hence, the expressions that equivalent to the given expression are, 3.4a + 5.6b and 5.6b + 3.4a
