Answer 2

Given :

Distance covered in 1 hour 30 min = 112 Km

To Find :

How many kilometers will the train travel in 4 hour 45 minutes.

Solution :

Train travel 112 Km in 1 hour 30 min

 ∴ 1 hour 30 min = 90 min

now, we need to convert 4 hour 45 min into minutes.

∴ 4 hour 45 min = (4×60 + 45) min

                           =  285 min

In 90 min, Distance covered by the Train = 112 Km

In 285 min, distance covered by the train = $\frac{112}{90}$ × 285

                                                                     = 354.67 km

∴ The Train travels 354.67 Kilometers in 4 hour 45 min.
