the answer
the speed of the train traveling in kilometers per minute can be found by using the following method:
v = 30 miles per hour
1 mile = 1.6 kilometers
just do the calculus by changing miles to kilometers
1 mile = 1.6 kilometers, so 30 miles= 1.6 km x 30 = 48 km
so the speed of the train is
v=30 miles / hour = 48km / h = 48km / 60 mn = 0.8 km/ mn
the answer is
C- 0.8 km/min
