See what you can do with the others.
answer:
speed= 72 km - per • hour
The answer is 30, assuming it is a cube,
First we have 2 types of units of measurement so let’s make all the same type.
600mm= 60 cm
500mm= 50 cm
Tray dimensions are 60 by 50 cm and is a rectangle
Cake tin is round and has diameter 25 cm
We can fit 2 rows and 2 columns of tins
Since (25+25) is less or equal to 50
And (25+25) is less or equal to 60
Answer 4 cake tins
