Best ResponseYou've already chosen the best response.0The answer is C) Method 1: There are 60 minutes in an hour, so 4 x 15 minutes 3 hours = (15 x 4) x 3 = 15 x 12 So there are 12 blocks of 15 minutes in 3 hours. You can then do: 12 x 42 = 504 km The train travels 504km in 3 hours. Method 2: 42 km in 15 15 x 4 = 1 hour and 42 x 4 = 168 so, it travels 168km in an hour 168(km) x 3(hours) = 504km in 3 hours

Best ResponseYou've already chosen the best response.0\(15 ~min = 0.25 ~h\) \(\dfrac{42~ km}{15~min} = \dfrac{42~km}{0.25~h} = 168 \dfrac{km}{h} \) \(168 \dfrac{km}{\cancel h} \times 3~\cancel h = 504~km\)
