Answer 8

Do problems 2 or 3 talk about the car?

Answer 9

what car are they talking about, and what is the car doing?

Answer 10

Well there was a problem for #3:
If a car has traveled 35 km in half an hour, what is the average speed?

Answer 11

For that problem, I got 70km/hr?

Answer 12

yes. #3 the car averages 70 km/hr over that 1/2 hour.
To average 70 km/hr it either goes a steady 70 km/hr or it goes slower and then faster.
But it is possible for it to go exactly 70 km/hr the entire 1/2 hour
Now if the car stops for enough time, its average speed goes down.
if it waits long enough its average speed will go down to 2 km/hr
it can then start up and travel at 2 km/hr the rest of its journey.

Answer 13

So I would say yes, the car could average 2 km/hour without exceeding 70 km/hr
