Hi.

For task a), you must take into account the break. The average speed is determined by sharing the entire route through the time required:

Task b is correct.

Task c also looks good.

at a, however, is the entire time 90′ and not 80′. The Average speed the smaller the larger the break is. Why are you taking the break? Don’t think that’s what that means.

Don’t be careful, of course. Thank you.

I didn’t take care of a, see comment from isohypse. It must be divided by 90 min (=1.5 h), not by 80 min

At b, however, the pause at the average speed should be taken into account.

Okay, I’m calmed.

(a)

If you take a break, the speed will be lower on average. You don’t have to take the break out. The mean speed is 40km/1.5h = …

b) is correct, only where the arrow shows 32km/h not the mean speed

c) I have not looked at

because the formula you write at a) doesn’t fit for a: you get something wrong with this one at a). But it is the formula you should use for b). Where this confusion comes from, I can’t say.
