Answer:
81 km
Step-by-step explanation:
Speed = distance / time
speed and time are measured in different units, thus, time has to be converted to seconds
60 second = 1 minute
90 x 60 = 5400 seconds
15 m /s = distance / 5400 seconds
distance = 81,000 metre
1000m = 1 km
81000 / 1000 = 81km
Answer:
y = 75x - 747
Step-by-step explanation:
formula is y = mx + b
m is slope
slope = change in y / change in x = (-597 - -672) / (2 - 1) = 75 / 1 = 75
m = 75
Now, to find b, substitute any value from the table. Let's do (1, -672)
y = 75x + b
-672 = 75(1) + b
-747 = b
So equation is y = 75x - 747
