15 minutes; First, you do 1,200-300, since he has already typed 300. (1200-300=900) Then you divide 900 by the number of words he has typed (60), and you get 15.

The Seward family
2x+3y= 44.50---------1
The Sena family
3x+6y= 78-------------2
solve 1 and 2
2x+3y= 44.50 X2
3x+6y= 78 X1
4x+6y= 89
- 3x+6y= 78
x+ 0= 11
x= 11
put x= 11 in 1
2x+3y= 44.50
2*11+3y= 44.5
22+3y=44.5
3y= 44.5-22
3y= 22.5
y= 22.5/3
y= 7.5
Hence Adult ticket is $7.5 while a child's ticket is $11
Answer:
Oil supply will run out in 44.283 years.
Step-by-step explanation:
There are 1.338 trillion barrels of oil in proven reserves.
If oil consumption is 82.78 million barrels per day then we have to calculate the number of years in which supply of oil runs out.
In this sum we will convert 1.338 million barrels of oil into million barrels first then apply unitary method to calculate the time in which oil supply runs out.
Since 1 trillion = million
Therefore, 1.338 trillion = 1.338× million
∵ 82.78 million barrels oil is the consumption of = 1 day
∴ 1 million barrels oil is the consumption of = day
∴ 1.338× barrels will be consumed in = days
= 16163.3245 days
≈ years
≈ 44.283 years
Therefore, oil supply will run out in 44.283 years
