The average speed is defined as the total distance travelled by the object in a particular interval of time. It can be calculated by dividing the total distance travelled by the total time taken.
So, Average Speed = total distance / total time
Here,
Let the total distance is 100 km.
Therefore, consider she will travel 60 km at speed of 60 kmph , 30 km at speed of 30 kmph and 10 km at speed of 10 kmph.
she will required times of 1 hour, 1hour and 1hour

Answer:
Possible dimensions are 16 × 4 inches and 32 × 2 inches.
Step-by-step explanation:
We are given that,
Area of the frame = 64 inch² = Length × Width
Now, we have that 64 can be factored as,
64 = 32 × 2
64 = 16 × 4
64 = 8 × 8
Since, the frame is in a rectangular shape. So, we reject the possibility of 8 × 8 inches frame.
Thus, the possible dimensions are,
Set 1: 16 × 4 inches
Set 2: 32 × 2 inches.
