Answer:
53 1/3 km/h
Step-by-step explanation:
average speed = (total distance)/(total time)
average speed = distance/time
time * average speed = distance
time = distance/(average speed)
250 km at 75 km/h
distance = 250 km
time = (250 km)/(75 km/h) = 3.33333... hours
350 km at 70 km/h
distance = 350 km
time = (350 km)/(70 km/h) = 5 hours
200 km at 30 km/h
distance = 200 km
time = (200 km)/(30 km/h) = 6.6666... hour
total distance = 250 km + 350 km + 200 km = 800 km
total time = 3.33333... hours + 5 hours + 6.66666... hours = 15 hours
average speed = (total distance)/(total time)
average speed = (800 km)/(15 hours)
average speed = 53 1/3 km/h
Answer:
It is linear
Step-by-step explanation:
If you graphed it it would be in a strait line. You also want to make sure that you write your answer in slope intercept form (y = mx + b). Your line would have to be y = -3x + 7 to be in slope intercept form.
Let the digits be x and y
Given that- xy= 18 and x+y=9
SO y= 18/x
And x+(18/x)=9
x^2 -9x+18=0
(x-6)(x-3)=0
So x=6,3
