12 is the answer to this question
Step-by-step explanation:
cars : trucks = 3 : 5
there are 3 + 5 = 8 parts of the whole that is shared between cars and trucks.
these 8 parts (or the whole) are in total 360.
therefore, 1 part = 360/8 = 45
cars get 3 parts of the whole parking lot, that is
45 × 3 = 135 cars
trucks get 5 parts of the whole parking lot, that is
45 × 5 = 225 trucks
1. 45/6 = 7.5
7.5*10 = 75
So the penguin walks 75 ft in 45 seconds.
2. 45/10 = 4.5
4.5*6 = 27
The penguin takes 27 seconds to walk 45 ft.
