## help!

"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

## Question 1

1:

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
