Answer:
900 miles
Step-by-step explanation:
Given:
Total time taken by Kris is 14 hours.
Speed of Kris is, Speed = 75 mph
Time spent while taking a break is 2 hours.
So, time Kris drove his vehicle is given as the difference of total time and time spent in break. Therefore,
Actual time of driving = 14 - 2 = 12 hours.
Now, distance traveled is given as the product of speed and time of driving.
∴ Distance = Speed Time
Distance =
Therefore, Kris drove 900 miles.
q + d = 80
.25q + .10d = 14.45
q. + d= 80
25q + 10d = 1445
-10q. - 10d = -800
25q + 10d = 1445
15q. = 645
q = 43 quarters
43 + d = 80
d= 37 dimes
