6. Columbus' ships covered approximately 144 miles a day. How many miles would they have traveled in nine days? What was the average speed per hour? If there were two days when the weather did not permit movement, how many miles a day would they have to travel to make up the time if they needed to cover the same amount of miles? Under these conditions, what would the average speed per hour be?

6. Columbus' ships covered approximately 144 miles a day. How many miles would they have traveled in nine days? What was the average speed per hour? If there were two days when the weather did not permit movement, how many miles a day would they have to travel to make up the time if they needed to cover the same amount of miles? Under these conditions, what would the average speed per hour be?

In nine days they would have traveled 1296 miles
Average speed per hour = 144 dived by 24 which gives you 6 miles per hour
The third part I don't understand

Answer 1

They would have to go 1296 miles in 7 days.

1296/7 miles/day
1296 / (7*24)miles/hour

Answer 2

a person jogs on a curvy trail six miles in one hour 6 miles/hour would be their

speed
average velocity

Answer 3

To calculate the number of miles Columbus' ships would have traveled in nine days, you need to multiply their average distance covered per day by the number of days.

So, 144 miles per day multiplied by 9 days equals 1296 miles.

To calculate the average speed per hour, you first need to convert the average daily distance into miles per hour. Since there are 24 hours in a day, divide the average daily distance (144 miles) by 24. This gives you 6 miles per hour.

Now, let's move on to the third part of the question. If there were two days when the weather did not permit movement, those two days need to be subtracted from the total number of days (9 days) given in the original question. So, the new total number of days under these conditions would be 9 - 2 = 7 days.

To make up for the lost time and cover the same amount of miles (1296 miles) within the remaining 7 days, divide the total number of miles (1296 miles) by the new total number of days (7 days):

1296 miles ÷ 7 days = 185.14 miles per day

Therefore, if Columbus' ships needed to cover the same distance with two days less, they would need to travel approximately 185.14 miles per day.

To calculate the average speed per hour under these conditions, divide the new average daily distance (185.14 miles) by 24:

185.14 miles ÷ 24 hours = 7.71 miles per hour

So, under these conditions, the average speed per hour would be approximately 7.71 miles per hour.
