Average speed = total distance divided by total time.
In the first part, the car covered 490 km in 7 hours, but I think you mistyped the second part (“then covers a speed of 90km”) and a critical piece is missing to find the total distance and time.
Answer:
20 cm^2
Explanation:
Degree of area you want to find: 80
Length of radius: 9
Equation: 80/360 times 9

.2222222... times 9 = 20
So the answer is 20 cm^2
