Two trains leave towns 346 miles apart at the same time and travel toward each other. One train travels 11 mi/hr faster than the other. If they meet in 2 hours, what is the rate of each train?

Question

We are suppose to use a linear equation and i just cant get this.

Answer 1

They travel a combined distance of 346 miles in 2 hours..

346 = 2r + 2(r+11) <--- r is the speed of the slower train

346 = 2r + 2r + 22

346 = 4r + 22

324 = 4r

r = 81

2(81+92) = 2*173 = 346

81 mph and 92 mph
