The answer is 2498.4km/h
The speed is
1 m = 0.001 km ⇒ 694 m = 694 * 0.001 km = 0.694 km
1 h = 60 min = 60 * 60 s = 3600 s
Therefore:
*assuming the pool is filled at a constant, steady rate*
*we can immediately see that if
then in half the time (divide both by 2)
and again in half of that time (divide by 2 again)
now to find 5/8, we simply multiply 1/8 by 5
Step-by-step explanation:
the answer is B negative for -2
