First, we need to convert the time of 1 hour and 24 minutes into minutes. Since there are 60 minutes in an hour, 1 hour and 24 minutes is equivalent to 1 * 60 + 24 = 84 minutes.
Now we can find out how much cloth 15 weavers can weave in 60 minutes by dividing the cloth length woven in 84 minutes by 84 and then multiplying the result by 60.
Let's call the length of cloth "L"
L = (15 * 84) / 60 = 21
So, 15 weavers can weave 21 units of cloth in 60 minutes.
If we want to find out how many weavers will be required to do the same job in 60 minutes, we can divide the length of the cloth by the number of weavers.
15 weavers = 21 units of cloth
So, the number of weavers required to weave the same amount of cloth in 60 minutes is 21/15= 1.4
So, 1 more weaver will be required to do the same job in 60 minutes.
