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.

300/4.5 = about 66.67

you traveled at 67 mph

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. Divide 4.5 from 4.5 and do the same thing for 300. You get 1 hour = 66.6 miles (decimal repeating), since you to simplify to the nearest whole number you get 67 miles. I hope this makes sense.
