Two tranis leave memphis at the same time, the first proceeding north and the second west.?

Question

the second trains has a speed 10 km per hour greater than the speed of the first train.if the trains will be 150 km apart at the end of 3 hours, determine the rate of each train.

Answer 1

I'm thinking the train would go anywhere from 65.7 to 78.6 MPH, but that's just my own little opinion.

Answer 2

30 and 40 kph

in a right triangle, which this would be, a^2 plus b^2 equals c^2

150 squared = 22500

30 x 3 (hours) = 90, squared is 8100

40 x 3 = 120, squared is 14400

8100 + 14400 = 22500

done!

Answer 3

It's a trick question.  Memphis is in the USA, and American railroads would stop running before they'd accept the use of the metric system.  Therefore the trains cannot exist.

Answer 4

I don't know the rate but the first train will be in Effingham, Illinois and the second train will be in Little Rock
