"1. A train travels 35 miles per hour for 170 minutes
How far will the train travel in this time?
A car completed this same journey in 60% of the time the train took
Find the average speed of the car in mph
2. Y is inversely proportional to X². When Y=4, X=3.
Find an equation linking X and Y.
If X = 6 find the value of Y. (Hint, use the equation you've found above)"
there's no words to explain how confused i am right now
In this case, the speed is 35 mph, and the time is 170 minutes ( hours)
so the distance that the train travels is miles.
The car traveled 99.167 miles in 60% of 170 minutes.
So it travelled 99.167 miles in minutes ( hours)
Therefore the average speed is mph
