First you divide them all by 7 to see which are greater than 19
28/7=4
84/7=12
35/7=5
105/7=15
even if you add 1 to them they all are still less than 19
so select them all
hope this helps! :)
Nine hundred thirteen thousand
Answer:
3.33 miles per hour
Step-by-step explanation:
The total distance traveled by the hiker is 5 * 2 = 10 miles, and the total time travelled is 2 + 1 = 3 hours.
So, to find the average speed of the entire trip, we can use the formula:
distance = speed * time
With distance = 10 and time = 3, we have:
10 = speed * 3
speed = 10/3 = 3.33 miles per hour.
