Convert to hours, then days, then years
60 minutes per hour
1000000/60=50000/3=16666.7 hours
24 hours per day
16666.7/24=694.4 days
365 days per year
694.4/365=1.9
the average person lives at least 1.9 years
maybe, I guess
Answer:
(7y + 3x)(7y - 3x)
Step-by-step explanation:
a² - b² = (a + b)(a - b)
49y² - 9x² = (7y)² - (3x)² {a = 7y ; b - 3x}
= (7y + 3x)(7y - 3x)
Since both 4 and 6 are divisible by 2, it becomes 2/3<span />
Answer:
Step-by-step explanation:
- Speed in one direction = 40 km/h
- Speed on return = x
- Average speed = 60 km/h
Let the distance be d
<u>Average speed </u>
- 2d/(d/40 + d/x) = 60
- d/40 + d/x = 2d/60
- 1/40 + 1/x = 1/30
- 1/x = 1/30 - 1/40
- 1/x = (4-3)/120
- 1/x = 1/120
- x = 120 km/h
