David runs at a speed of 5 meters per second and covers a distance of 700 meters.
For how long does David run?
To solve this problem, we'll follow these steps:
Now, let's work through each step:
Step 1: The problem provides us with a speed of meters per second, and a distance of meters.
Step 2: We'll use the formula to find the time.
Step 3: Substitute the given values into the formula:
.
Compute the division:
seconds.
Therefore, David runs for seconds.

David runs at a speed of 5 meters per second and covers a distance of 700 meters.
For how long does David run?
Think of it this way: if you travel 5 meters every second, how many seconds do you need for 700 meters? You need 700 ÷ 5 = 140 seconds. Speed tells you how much distance per unit time!
Always check your units first! If distance is in kilometers and speed is in meters per second, convert one to match the other. Your final answer's units come from distance units ÷ speed units.
Use the triangle method: Draw a triangle with D on top, S and T on bottom. Cover what you want to find:
Yes! To convert: 140 ÷ 60 = 2 remainder 20, so that's 2 minutes and 20 seconds. Always double-check if the problem asks for a specific time unit.
Decimal answers are perfectly fine! For example, if you got 3.5 seconds, that means 3 and a half seconds. Just make sure your calculation is correct and the units make sense.
