Do you want to solve for:

The above 3 formulas are used for solving problems involving distance, velocity and time. If you know 2 of the 3 variables the third can be calculated.
As usual, here at www.1728.com, we have a calculator that will do all the work for you.

This ultra calculator is special by allowing you to choose among a great variety of units (12 per category). Unlike other calculators, you are NOT confined to inputting distance in feet, time in minutes, etc. making this calculator quite versatile. Let’s see some examples.

1) You can run the 100 yard dash in 12 seconds. What is your velocity in miles per hour?
The most important step in using this calculator is:
FIRST CHOOOSE WHAT YOU ARE SOLVING FOR
In this case we are solving for VELOCITY, so click on that button.
Enter 12 in the “time” box and choose seconds from its menu.
Enter 100 in the “distance” box and choose yards from its menu.
Click the CALCULATE button and you will see this equals 17.045 miles per hour. PLUS you get to see the answer in 11 other different units !!

2) A glacier moves at about 0.0009513 mm per second. How long does it take a glacier to move 1 mile?

FIRST CLICK ON WHAT YOU ARE SOLVING FOR – TIME
Enter 0.0009513 in the velocity box and choose millimeters per second from its menu.
Enter 1 in the distance box and choose miles from its menu.
Click CALCULATE and your answer is 53.6 years (as well as 11 other units).

3)You are watching the Indianapolis 500 Auto Race and a car has just taken 50 seconds to complete one “lap” of the track at 180 miles per hour. How long is the race track?
FIRST CLICK ON WHAT YOU ARE SOLVING FOR – DISTANCE
Enter 180 in the velocity box and choose miles per hour from its menu.
Enter 50 in the time box and choose seconds from its menu.
Click CALCULATE and your answer is 2.5 miles (or 13,200 feet or 158,400 inches ,etc.)

Here’s hoping this calculator helps you with those math problems.

Numbers are displayed in scientific notation with the amount of significant figures you specify in the box above. For easier readability, numbers between .001 and 1,000 will not be in scientific notation but will still have the same precision.
Internet Explorer and most other browsers, will display the answers properly but there are a few browsers that will show no output whatsoever. If so, enter a zero in the box above. This eliminates all formatting but it is better than seeing no output at all.
