A unit rate is any quantity's value with respect to another. An example is speed expressed in kilometers per hour which is used to measure how fast a vehicle is traveling.
Answer:
The average speed of the trip there is <u>86 mph.</u>
Step-by-step explanation:
Given:
Time taken to reach Portland = 3 hours
Time taken to come beck from Portland = 6 hours
Average speed for the returning trip = 43 mph
Distance traveled for the returning trip can be obtained by multiplying the returning speed by returning time. Therefore, distance for returning trip is:
Now, distance traveled for the return trip is same as going to the trip.
So, distance traveled by Jessica going to Portland = 258 miles.
Time taken to go there = 3 hours
Therefore, speed of the trip there is given as the ratio of distance and time and is given as:
Therefore, the average speed of Jessica's car to go to Portland is 86 mph.
