Answer:
The speed of Kali is 30 mph.
Step-by-step explanation:
Let, the speed of Kali be "x", then speed of Ndiba will be:
Speed of Ndiba = x + 15 mph
If, the time for travel for Ndiba is 2 hrs, when he catches Kali, and he left 1 hour later than Kali, then then time traveled by Kali at that instant will be 2+1 = 3hrs.
At the point of meeting both will have covered same distance.
Distance Covered by Kali = Distance Covered by Ndiba
(Speed of Kali)(Time traveled by Kali) = (Speed of Ndiba)(Time traveled by Ndiba)
(x)(3) = (x +15)(2)
3x = 2x +30
<u>x = 30 mph</u>
The correct answer is, actually 30 mph, by the solution shown above.
Answer:
135 cent
Step-by-step explanation:
Given that:
Cost of electricity = 10cent / 1 kilowatt hour
TV consumption = 150watt per hour
Duration = 3 hours
Cost of operating for 30 days
Total energy usage per day: (150 watt/hr) * 3 hours = 450 watts = 450/1000 = 0.45kW
Total energy for 30 days = 0.45 * 30 = 13.5 Kilowatt
Cost per kilowatt = 10cent
13.5 kw = 13.5 * 10 cent = 135 cent
135 cent = $1.35

Answer:
of a sheet of paper
Step-by-step explanation:
Hi!
This isn't the easiest to explain with numbers but I'll do it with an example instead.
If you had 60 cookies and had to split it equally with you and one of your other friends, how would you do it?
You would do 
, right? Because you have 60 cookies and you're dividing it amongst 2 people.
It's the same idea here!
We take the number of sheets of paper, and we divide it by the number of people we have to share it with.
so we do . You don't even have to simplify in this case because this is a fraction and this is the simplest form of this fraction as well
I hope this made sense, let me know if you have any questions
