Hope it helps!! Mark this answer as brainliest if u found it useful and follow me for quick and accurate answers...

Step-by-step explanation:

$Speed = \frac{ Distance}{ Time} \\ \\ \red{ ∴ Time = \frac {Distance}{Speed}}$

------------------------------------

$Time = \frac{560}{32} = 17.5 \: \: hr$

------------------------------------------------------

$Time = \frac{240}{45} = 5.33 \: \: hr$

------------------------------------------------------

$12 \: \: km = 12000 \: \: m \\ \\ Time = \frac{12000}{12} = 1000 \: \: sec$

Answer 2

1.17..5hrs

2.5.33hrs 3.16.66hrs

1.T = D/S= 560/32

= 17.5 hrs

2. T=D/S=240/45

=5.33 hrs

3.T=D/S=12000m=12km/12

=1000m=16.66hrs
