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

Answer:

140 mile

Step-by-step 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.

Answer 2

The speed of the first train is 50 miles per hour while the second train is at 60 miles per hour.

Speed

Speed is the ratio of total distance to total time taken. It is given by:

Speed = distance / time

Let a represent the speed of the first train. In two hours:

a = d₁/2

d₁ = 2a

a + 10 = d₂/2

d₂ = 2a + 20

d₁ + d₂ = 220

2a + 2a + 20 = 220

4a = 200

a = 50 miles per hour

The speed of the first train is 50 miles per hour while the second train is at 60 miles per hour.
