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
