1. At a speed of 80km/h, it takes 10hrs to travel between Abuja and Lagos. How long will it takes to cover the same distance at the speed of 100km/h?
2 answers:
Answer:
1) 8 hours
2) 12 pumps
Step-by-step explanation:
1)
Distance travelled=800 km
Because if you use the speed distance time triangle, 80*10=800
We can then use this to find out how long it would take to travel it at a different speed.
800km/100=8 so it takes <u><em>8 hours</em></u>
2)
36*3=108 so if there was only one pump, it would take 108 hours to fill the pool.
108/9=12 so you would need <u><em>12 pumps</em></u>
Answer:
1. 8 hours 2. 12 pumps
Step-by-step explanation:
1. 80 ×10=800
there are 800 miles between abuja and lagos
800÷100=8
it will take 8 hours
2. with 3 pumps it takes 36 hours. you need to be 4 times quicker so you need 4 times more pumps.
4×3=12 pumps

Yes, if you divide it by fractions of pi, then you would get even integers.
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.
This is same as (4x-6)(2x), so you can distribute 2x into 4x-6 and you would get8x² - 12x Final answer: 8x² - 12x
Answer:
(4x3)+(5x3)=12+15=27
Step-by-step explanation:
You can multiple both by any number as long as it adds to nine. 4 plus 5=9.
You can also do 3+6=9, or 8+1=9
