Homework problem....

Please can you help me with this problem.
I don't understand what its asking and I don't know where to begin :

It says : A car travels at a speed of 50mph from point A to B.
The distance travelled is 1200 km. How long does the journey take ?

Thanks guys for any help !

They want you to find the travel time. Use Distance = Speed X Time. Beware of units.

1200 kilometers (km) × 0.621 = 745.2 miles (mi).
distance=rate*time (in same units)

$$\frac{745.2 miles}{50\frac{miles}{hour}} =$$
