Answer:
7.8. 10 ^ 3 m / s
Step-by-step explanation:
The computation of the average speed in m/s is shown below:
The average speed equation is
= ΔS ÷ Δt;
As We know that
an entire revolution would be40,000 km
and a satellite takes 85 minutes to complete a revolution,
So,
ΔS = 40,000 km = 40,000,000 m
Δt = 85 min = 5 100 s
Now the average speed is
= 40 000 000 ÷ 5 ÷ 5 100
= 7843.14 m / s
= 7.8. 10 ^ 3 m / s
Answer:
-2
Step-by-step explanation:

3/4 inch represents 1/8 mile, that means:
1/8 mile represented by 3/4 inch
1 mile will be : (3/4) inch ÷ (1/8)
= 3/4 × 8/1 = 6
1mile will be represented by 6 inches
So on the map it is 6 inches per mile
