A hiker climbs a 5-mile trail up a mountain in 2 hours. On the return trip downhill, she walks the same trail and returns to her
starting point in 1 hour. What was her average rate of speed, in miles per hour, for the entire trip?
1 answer:
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.

12:15 does not belong, since that is a ratio of 4:5, whilst the others are all 3:4.
If it's 4 less than 2 times a number if would be

T-shirt costs $4
Sweater costs $4(4)
Sweater costs 4 x 4
4 x 4 = 16
Sweater costs $16
