Question

Symbols The difference in speeds of El Toro and T Express is 5 miles per hour. If El Toro has the greater speed, write and solve a subtraction equation to determine its speed.

Answer 1

Answer: Let's call Vt and Ve to bout velocities.

you know that Vt>Ve and that Vt - Ve=5

so Vt = 5 + Ve.

and you can check that Vt is 5 miles per hour greater than Ve.

So if you know the vale of Vt or the value of Ve, with that equation you can obtain the other velocity.

Answer 2

Let the speed of El Toro be x mph and that of T Express be y mph.

Given : Speed of El Toro > Speed of T Express

i.e, x > y

Also, the difference in the speeds of El Toro and T Express is 5 mph.

So, the required equation is

x - y = 5

To determine the speed of a train, the speed of other is required.

The speed of El Toro = Speed of T Express + 5

The speed of T Express = Speed of El Toro - 5
