Arental company can set up 3 small tents and 1 large tent in 115 min. they can set up 2 small tents and 2 large tents in 130 min how much time is required to set up a small tent

25 Minutes

Explanation:

Let time to setup small tent be denoted by S

Let time to setup Large tent be denoted by T

From the given information:

3S + 1T = 115   -- i

2S + 2T = 130 -- ii

Now these are two linear equations which can be solved

from (i)

T = 115-3S

add value of T in (ii)

2S + 2(115-3S) = 130

2S + 230 -6S = 130

Solving for S

4S = 100

S= 25
