Working alone, it would take Shandra 40 minutes to sand a table. To sand the same table, also working alone, it would take Kelly 1 hour. If they work together, the situation can be modeled by the following equation, where t is the time it would take to sand the table working together. StartFraction 1 Over 0.75 EndFraction + StartFraction 1 Over 1.25 EndFraction = StartFraction 1 Over time to complete together EndFraction Shandra claims it will take them about 50 minutes working together, because 50 is the mean of 40 and 60. Which best describes Shandra’s claim?
