Step-by-step explanation:
<span>Find the round trip distance:
4.95 km/hr * 48 min * 1 hr/60 min = 3.96 km
1.98 km each way
d = r*t
t = d/r = 1.98/4.5
t = 0.44 hrs upstream
t = 26.4 minutes upstream</span>
the set of solutions of the equation |f(x)|=a
is always equivalent to sum of sets of solutions of equations:
f(x)=a
and
f(x)=-a
therefore correct answer is the first and the second equation
