Question

Junnie walked for 2.5 hours at a distance of 3.2miles per hour. Maurice walked for 1.8 hours at a speed of 4.1 miles per hour.

A. Who walked farther?
B. How much farther did that person walk?

Answer 1

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:

`speed= (distance)/(time)`

`distance = speed * time`

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.
