travis drove 129 miles in 3 hours.he drove at a constant speed.how many miles did he drive in 1 hour?
2 answers:
Answer:
43 miles
Step-by-step explanation:
Distance covered by Travis, d = 129 miles
Time taken by Travis, t = 3 hours
We need to find the distance covered by Travis in 1 hour. It can be calculated using unitary method.
129 miles in 3 hours
Distance covered in 1 hour is,
So, Travis covered a distance of 43 miles in 1 hour. Hence, this is the required solution.

The first thing we must do for this case is to define variables.
n = number of 5k races covered
f = end time.
We have the following equation:
f = -1.2n + 38.1
We note that the slope of the line is:
m = -1.2 minutes per race
Therefore, the time decreases 1.2 minutes when the number of races increases n.
Answer:
The model predicts that for each additional race to runner has run, the finishing time decreases by about 1.2 minutes
