Final answer:
The hospital has 290 beds.
Step-by-step explanation:
In this question, we are given a hospital's bed to room ratio of 2:1 and we are asked to find the number of beds given a certain number of rooms. So, if the hospital has 145 rooms, we can use the given ratio to find the number of beds.
To find the number of beds, we can set up a proportion:
2/1 = x/145
Cross-multiplying, we get:
2 * 145 = 1 * x
Simplifying, we have:
x = 290
Therefore, there are 290 beds in the hospital.
