Answer:
Bob and Alice will meet after 5 minutes.
Step-by-step explanation:
Alice can speed walk at a speed of 8 km/h, and Bob walks at half her speed, which is 4 km/h.
Their speeds add up when they walk towards each other. Therefore, the total speed is 8+4=12 km/h.
The distance between their homes is given as 1 km
The time it takes for them to meet is equal to the distance divided by their total speed. Thus, the time in hours is 1/12 hours
Since there are 60 minutes in an hour, we multiply the time in hours by 60 to get the time in minutes. 1/12x60=5 mins
