Final answer:
The equation that can be used to find the number of hours remaining in Marilyn's drive is t = (d - s) / r, where t is the number of hours remaining, d is the total distance, s is the distance already driven, and r is the average rate of driving. Plugging in the values, we find that there are approximately 14.17 hours remaining in Marilyn's drive.
Step-by-step explanation:
To find the number of hours remaining in Marilyn's drive, we can use the formula:
t = (d - s) / r
Where:
t is the number of hours remaining in Marilyn's drive
d is the total distance from her home to her destination, which is 970 miles
s is the distance Marilyn has already driven, which is 120 miles
r is the average rate at which Marilyn is driving, which is 60 miles per hour
Plugging in the values into the formula, we get:
t = (970 - 120) / 60
t = 850 / 60
t = 14.17
Therefore, there are approximately 14.17 hours remaining in Marilyn's drive.
