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: 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.

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
