Question

You are driving home from the school steadily at 95 km/h for 180 km. It then begins to rain and you slow to 65 km/h. You arrive home after driving 4.5 h. How far is your hometown from school? What was your average speed?

Answer 1

Ответ:

Let's first calculate the distance you traveled at each speed. Since you drove for 1.5 hours at 95 km/h, you covered a distance of:

1.5 hours * 95 km/h = 142.5 km

Then, you drove for 3 hours at 65 km/h, covering a distance of:

3 hours * 65 km/h = 195 km

To find the total distance you traveled, we add these two distances:

142.5 km + 195 km = 337.5 km

Therefore, your hometown is 337.5 km from school.

To calculate your average speed, we divide the total distance you traveled by the total time you spent driving:

337.5 km / 4.5 hours = 75 km/h

Therefore, your average speed was 75 km/h.
