Answer:
300km
Step-by-step explanation:
To find the total distance traveled within the given time frame, we need to known that distance is the product speed and time;
Distance = Speed x time
For the first lap:
Distance = 100km/hr x 3hr = 300km
For the second lap;
Distance = 150km/hr x 2 = 300km
Distance = 300km + 300km
So;
Distance = 300km
