Question

Ken Runfast is the star of the cross-country team. During a recent morning run, Ken averaged a speed of 5.69 m/s for 11.3 minutes. Ken then averaged a speed of 6.31 m/s for 8.7 minutes.

Determine the total distance which Ken ran during his 20 minute jog.

Answer 1

Ken ran a total distance of approximately 7154.44 meters during his 20 minute jog.

Step-by-step explanation:

To find the total distance Ken ran, we can use the formula:

distance = speed x time

First, let's convert the time to seconds:

11.3 minutes = 11.3 x 60 = 678 seconds

8.7 minutes = 8.7 x 60 = 522 seconds

Now we can use the formula to calculate the distance:

distance1 = speed1 x time1 = 5.69 m/s x 678 s = 3863.62 m

distance2 = speed2 x time2 = 6.31 m/s x 522 s = 3290.82 m

The total distance Ken ran is the sum of the two distances:

total distance = distance1 + distance2 = 3863.62 m + 3290.82 m = 7154.44 m

Therefore, Ken ran a total distance of approximately 7154.44 meters during his 20 minute jog.
