Answer:
the answer is 448
Step-by-step explanation:
The total track lap time of the runner is 2 2/5 minutes or 2.4 minutes.
The total track lap time of the runner can be calculated by summing up the individual time spent at each pace (run, jog, walk). Each pace's time is first multiplied by the fraction of the lap completed at that pace.
For the run, the calculation is 2/5 of 1 minute which is 2/5 minute.
For the jog, the calculation is 1/2 of 5 minutes which is 5/2 = 2 1/2 minutes or 2.5 minutes in decimal form.
For the walk, the calculation is 1/10 of 7 minutes which is 7/10 = 0.7 minutes.
Adding these times together gives a total of (2/5) + (5/2) + (7/10) = 12/5 = 2 2/5 minutes or 2.4 minutes in decimal form.
