The distance between st. louis and chicago is 300 miles. it takes me 4.5 hours to travel between these two cities. what speed did i travel at? round your answer to a whole number.

67 mile per hour

Step-by-step explanation:

You have 4.5 hours = 300 mile (Between St. Louis and Chicago), so you have to figure how much miles you travel in 1 hr., since the question says what speed the person travel at.

So:

All of which have the same probability.

Required

Determine the probability of 1, then 2 when spin twice

The probability of the first being 1 is:

The probability of the second being 2 is:

So, the required probability is:
