Question

Jeremy's house has a big yard. When Jeremy cuts the grass he always asks his little brother to help him. When they work together, it takes them about 1.25 hours to cut the yard. When Jeremy has to do it alone, it takes him 1.5 times longer

Answer 1

Jeremy and his brother take 1.25 hours to mow their big yard together. If Jeremy works alone, it takes him 1.5 times longer, resulting in 1.875 hours or 1 hour and 52.5 minutes to mow the yard on his own.

Step-by-step explanation:

The question provided discusses a situation about Jeremy and his little brother mowing the big yard of their house. It is stated that when they work together, it takes about 1.25 hours to mow the yard. However, when Jeremy works alone, it takes him 1.5 times longer to complete the task. We can calculate the time it takes for Jeremy to mow the yard alone by multiplying 1.25 hours by 1.5, which would be 1.875 hours or 1 hour and 52.5 minutes.

Step-by-Step Calculation:

1. Determine the base time taken when Jeremy and his brother work together, which is 1.25 hours.
2. Calculate the time it takes for Jeremy to work alone by multiplying 1.25 hours by 1.5, which equals 1.875 hours.
3. Convert the decimal time to minutes to get the full time in hours and minutes.
