A runner has a track lap time of 1 minute while at a run,5 minutes while at a jog, and 6 minutes while at a walk. If 1/15 of the lap is paced at a run,1/3 at a jog, and 3/5 at a walk, what is the total track lap time of the runner? Write the solution as a mixed number or a fraction in lowest terms.

Answer 1

What is the total track lap time of the runner?

Write the solution as a mixed number or a fraction in lowest terms.

RUNS 1 LAP IN 60 SECS

1/15 OF A LAP = 1/15 * 60 = 4 seconds

JOGS 1 LAP IN 5 MIN = 300 SECS

1/3 OF A LAP = 1/3 * 300 = 100 seconds

WALKS 1 LAP IN 6 MIN = 360 seconds

3/5 OF A LAP = 3/5 * 360 = 216 seconds

Adding 4 sec + 100 sec + 216 sec = 320 sec

320 seconds = 320/60 = 5 1/3 MINUTES

ANSWER: 5 1/3 MINUTES
