Question 965447
Let the speeds of the trains be x and 2x respectively.
Distance=Speed*time
Distance covered by the first train in 5 hours=x(5)=5x
Distance covered by the second train in 5 hours=2x(5)=10x
Total distance covered=495 miles
5x+10x=495
15x=495
x=33 miles/hour
The speeds of the trains are 33 mph and 66 mph.
Distance covered by the first train=33(5)=165 miles
Distance covered by the second train=66(5)=330 miles
