Answer:
<em>The slowest train goes at 86 mph and the fastest train goes at 96 mph.</em>
Step-by-step explanation:
<u>Distance and Speed</u>
Assume x is the speed of the slowest train, therefore the speed of the fastest train is x+10.
The distance is calculated as:
d = vt
Where v is the speed and t is the time.
The distance traveled by each train in 5 hours is:
Slowest: 5x
Fastest: 5(x+10)
The sum of both distances is 910 miles:
5x + 5(x + 10) = 910
Operating:
5x + 5x + 50 = 910
10x = 910 - 50 = 860
x = 860/10
x = 86
The slowest train goes at 86 mph and the fastest train goes at 96 mph.
Y=-12
explanation multiply x by -3 to get y
Answer:
720
Step-by-step explanation:
Given that
The person could lose approx 8 × 10 if there is hair strains each day
Based on the above information
The number of hair strains the average person could lose in nine days is
= 9 days × 8 × 10
= 720
hence, the number of strains required for loosing in nine days is 720 and the same is to be considered
