We are given speed and time for Junnie and Maurice.
We will use speed distance formula here to find the distance covered by Junnie and Maurice.
The formula is given by:
Distance covered by Junnie:
We are given speed of Junnie as 3.2 miles per hour and time taken by her is 2.5 hours.
Plugging these values to find distance:
Distance = 3.2 * 2.5 = 8 miles
Distance covered by Maurice:
We are given speed of Maurice as 4.1 miles per hour and time taken by her is 1.8 hours.
Plugging these values to find distance:
Distance = 4.1 * 1.8 = 7.38 miles
Distance covered by Maurice is 7.38 miles whereas that covered by Junnie is 8 miles.
(A) So it is clear that Junnie walked farther.
Now let us find how much farther did Junnie walked.
We can find that by finding the difference between the two distances.
Difference = Distance covered by Junnie - distance covered by Maurice
Difference = 8- 7.38 = 0.62
(B) So Junnie walked 0.62 miles farther.
