The time taken bu Castel to dig 10 ft by 10 ft hole = y = 6 hours
Let The time taken by both when they work together = z hours
<u>According to question</u>
The time taken by both when they work together = time taken by Ryan to dig 10 ft by 10 ft hole + time taken bu Castel to dig 10 ft by 10 ft hole
i.e =
+
Or, =
+
<u>Taking LCM</u>
Or, =
Or, =
Or, z = hours
∴ z = 2 hours 42 minutes
So, The time taken by both when they work together = z = 2 hours 42 min
Hence, The time taken by both when they work together is 2 hours 42 minutes . Answer
