Answer:
It will be worth $128.
Step-by-step explanation:
After 1 year, 3/5 of 800 is 480 which leaves the value at $320, and then after 2 years, 3/5 of 320 is 192. 320-192 leaves the value at $128.
Slope equals rise over the run
so if slope = 5 then the rise also equals 5 and the run is 1
Let the distance be x miles
Time = Distance / speed
Time taken by Mike to go to his friend's house = x / 40 hours
Time taken by him to return = x / 45 hours
Total time = x / 40 + x / 45 = 4 hours
= 9x + 8x = 1440 miles
17x = 1440
= x = 1440 ÷ 7
= x = 84.706
Time taken to return home = 84.706 /45= 1.882 hours .
Therefore , Mike took 1.882 hours to reach home .
