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. A swimming pool takes 36hrs to fill using three identical pumps. If the pool needs to be filled in 9hours, how many pump will be needed? Please I need my answer ASAP
To find this answer you have to divide 25% by 100, which equals 0.25. Now multiply 0.25 by 40 and you get 10$. Since 10$ was the discount, you just add 10$ + 40$, therefore 50$ is the original price.
