Carmen are traveling at the same speed. tonya drives 4 hours. carman drives another half hour and goes 15 more miles. which equation can be solved to find how fast the cars are going?

Alright, lets get started.

Suppose Tonya is driving at speed = x

As per given in question, Tonya drives 4 hrs, so distance covered by Tonya is :

Distance covered by Tonya = 4x

Carmen drived half hour more than Tonya means carmen drived 4.5 hrs.

The speed of Carmen is also = x

So, distance covered by Carmen = 4.5 x

As per given in question, carman drives another half hour and goes 15 more miles.

It means, distance covered by Carmen is 15 more than distance covered by Tonya.

So putting it into equation,
