Travel Planning with Equations

Using Equations to Organize a Trip

Algebra can help you plan trips! Figure out distance, time, and cost using simple equations.

Distance, Rate, and Time

The formula \( d = rt \) connects distance (\( d \)), rate (\( r \)), and time (\( t \)). If you know two, you can find the third.

Packing and Budgeting

Use variables to keep track of how many items you need or how much you can spend on souvenirs.

Real-World Value

Whether you’re planning a road trip or a family vacation, algebra makes your plans run smoothly and helps avoid surprises.

Examples

  • If you travel at 60 mph for 3 hours, \( d = 60 \times 3 = 180 \) miles.

  • If you have \$40 and want to buy \( x \) T-shirts at \$8 each, \( 8x \leq 40 \) tells you the most you can buy.
