Hello! Its probably my lack of understanding English, but how am I supposed to understand he had spent an hour at each of the 4 pools, and not all the 4 at one single hour?
thanks
44 Sally is helping her father dig worms for fishing. “That’s exactly enough,” he says as she places a worm in his tin.
“How many do you need?” she enquires.
“I use 4 worms on my hook and reckon on having to replace an average of one of these each time I cast. I cast 12 times an hour. Today I will fish 5 pools spending an hour at the first 4 and an hour and a half at the fifth. I always discard the worms on my hook when walking between pools.”
How many worms are in the tin?
