Step-by-step explanation:
Find the missing angle:
180⁰ - 82⁰ = 98⁰
Find the sum of the angles given without the missing angle:
180⁰ - 98⁰ = 82⁰
The sum of both the angles is 82⁰
Write an equation:
5x + 8 + 6x + 8 = 82⁰
Collect the like terms together
11x + 16⁰ = 82⁰
Subtract 16⁰ from both sides
11x = 66⁰
Divide by 11 on both sides
x = 6⁰
Answer: It will about 1.88 hours or 1 hour 52.5 minutes to clean the stadium if they work together .
Step-by-step explanation:
Given : Time taken by Kevin to clean a stadium = 5 hours
Rate of work done by Kelvin =
Time taken by Chris to clean a stadium = 3 hours
Rate of work done by Chris =
Let t be the time taken by both of them to clean the stadium together.
According to the question , we have
Rate of work done together = Rate of work done by Kelvin+Rate of work done by Chris

hours
[∵ 1 hour = 60 minutes]
Hence, It will about 1.88 hours or 1 hour 52.5 minutes to clean the stadium if they work together .
