The formula for Average speed = 
The car travels 80 km in 1 hour.
Then the car travels 90 km in 2 hours.
And finally the car travels 76 km in 1 hour
So the total distance covered by the car = 80 + 90 + 76 = 246 km
The total time taken to cover this distance = 1 + 2 + 1 = 4 hours.
So average speed = 
The average speed of the car is 61.5 km / h
Answer:
.
Step-by-step explanation:
The inverse is basically you just swapping x and y. People want to solve it for y to make it a function of x.

Swap x and y:

Now solve for y by dividing y on both sides:


.
7/8times16/1 gives 112/8, which is 14.
you multiply both numerators over both denominators.
