Answer:
90 km/h
Step-by-step explanation:
To solve this problem you first need to convert minutes to hours since the unit is km/h. Doing this we get half an hour (1 hour=60 mins so you divide 30 by 60) after converting you simply divide 45 by 1/2 or .5 to get the answer.
The answer for this problem is going to be 30 because you take the 50° that you already have and subtract 20° and you get 30
