Part of the problem is that students are told how to solve these kinds of problems rather than being taught to reason their way through the problem. I looked at it and 'reasoned' they will meet when the combined distance of both trains is 300 miles. No math required for that step. I believe most adults and kids could then figure out 50 MPH + 70 MPH = 120 MPH and 300 Miles/120 MPH = 2.5 Hours or am I giving people to much credit? |
