Answer:
a). 18 minutes
b). 8.4 miles
Step-by-step explanation:
a). Let Luis meet Kristina after the time = h hours
So the distance traveled by Luis in h hours = Speed × time
= 8×h
= 8h miles
If Kristin started after 45 minutes of hours then the distance traveled by her
= Speed × time
= miles
Since after h hours distances traveled by Luis and Kristin are same so,
28h - 8h =
20h = 21
h = 1.05 hours
So the time taken by Kristin = (h - 0.75)
= 1.05 - 0.75
= 0.30 hours ≈ 18 minutes
b). Distance traveled by Luis before Kristin catches Luis = 8×1.05
= 8.4 miles
