Question

question 14 (01.04 mc) lyla walks three times per week for 45 minutes at a speed of 4.0 miles per hour. she wants to increase her time. what should she do? (5 points) walk at 4.5 miles per hour. walk for 50 minutes. walk four times per week. walk up and down more hills. question 15 (01.04 mc) marti wants a more challenging workout session in the same 30 - minute exercise block. she currently uses 8 - pound weights during her strength training, and she is not ready to increase

Explanation:

Lyla wants to increase her walking - time. Walking at a faster speed (4.5 miles per hour instead of 4.0 miles per hour) will not increase time but may increase distance. Walking up and down more hills may increase intensity but not necessarily time. Walking four times per week increases frequency, not the time of each walk. Walking for 50 minutes instead of 45 minutes directly increases the time of her walk.

Answer:

Walk for 50 minutes.
