It took a car 3 days to travel 2245 miles. What was this car's average speed, in miles per hour? (round to the nearest mile per hour)

31 miles an hour

31 mph

Step-by-step explanation:

We know the total number of miles is 2245, over a 3 day period. If we convert 3 days into hours, we get 72 hours (3 x 24). Now we can do 2245 : 72, giving us 31.1805556. In this case we are rounding to the nearest mile, so we would put 31 miles.
