Question

PLEASE HELP OR ELSE MOM WILL BE REALLY MAD!!!!! Two trains, one going from Boston to New York and the other going from New York to Boston, started their trips at exactly same time. Speed of the first train was 10 mph less than twice the speed of the second train.How far from Boston station to have the Met in two hours, if the total distance between cities along the railroad is 220 miles?

Answer 1

140 mile

Explanation:

`d_(1) +d_(2) =220\\2(2x-10+x)=220\\x=40\\d_(1)=2*(2*40-10)=140mile`

While x is the speed of the second train.
