Question 757488: This question was assigned to me in my Physical Science college class.
- If a car travels 189km in 1 hour 30 minutes, what is its average speed?
this is how I tried to solve it, 189 divided by 90 equals 2.1, don't think that's correct?
Answer by fcabanski(1391) About Me  (Show Source):
You can put this solution on YOUR website!
Distance = rate times time.


189 = rate x 90


189/90 = 2.1 kilometers per minute = 2.1 * 60 = 126 kilometers per hour.


Your answer is correct.
