Circle nimber radius

Answer 2

It will take approximately 10 hours to travel by bus.

Step-by-step explanation:

To determine how long it will take to travel by bus, we need to calculate the time it takes to travel at the bus's speed. We can use the formula: time = distance / speed. Considering the distance is 800 km and the bus's speed is not given, we can assume it is 80 km/h (since it is not mentioned that any other vehicle is involved). Plugging these values into the formula: time = 800 km / 80 km/h = 10 hours. Therefore, it will take approximately 10 hours to travel by bus.
