Answer:
Approximately 26,82 meters per minute
Step-by-step explanation:
If 1 mile = 1609 meters, then the cheetah runs 1609 in 60 minutes, and we want to find the x meters it runs in 1 minute.
We do x = (1 * 1609) / 60 = 26,82 meters per minute ( approximately )
Answer:
x = -3
Step-by-step explanation:
4x+3 = 6x+9
4x-6x = 9-3
-2x = 6
x = -3
<span>Rate of pump A: 1/8 of a pool per hour
Rate of pump B: 1/9 of a pool per hour
Combined rate: 1/8+1/9 = 17/72 +1/9 = 25/72
So if they work together, the two pumps have a combined rate of 25/72 of a pool per hour (i.e in one hour, the two pumps will empty 25/72 of the pool)
</span><span>But we want to empty ONE pool (not 25/72 of one). So we need to multiply 25/72 by some number x to get 1.
</span>
<span>Now solve for x
x=2.88
</span><span>It will take the two pumps 2.88 hours to empty the pool.
2 hours 52 minutes 50 seconds</span>
