Answer:
the average speed of the whole journey is 45 km/h
Step-by-step explanation:
The computation of the average speed of the whole journey is shown below:
Average speed is
= (Speed 1 + speed 2) ÷ 2
= (60 km/h + 30 km/h) ÷ 2
= 90 km/h ÷ 2
= 45 km/h
Hence, the average speed of the whole journey is 45 km/h
We simply ignored the distance as it is not relevant for the given situation
The same would be considered
12+ 36x = 36x +12
Thai your answer
Step-by-step explanation:
Since, opposite sides of a rectangle are equal and each angle is of 90°.
QP = RS = 14 cm

Diagonals of a rectangle bisects each other.

So simply we are putting values in equation
A2 A=2.3
So A2 means 2.3 × 2.3
The answer is 5.29
