Answer:
3. The answer is a) 80 km/h
Explanation:
1.First, let us convert minutes to hours with respect to the twavel time, we have:
t = 30 minutes × 1hour and 60minute = 0.5 hours
2.Next, let us assume that the car starts from rest the traveld 40 km and 30 minutes we have:
s = 0 to 40 km
s = 40 km - 0 = 40km
Or the total distance covered is 40 km
3.Now, we are to solved for the average speed, Let us use the formula and substitute the given information, we have:
v = s/t
v = 40 km/0.5 hour
v = 80 km/h
Therefore, the average speed is 80 km/h
