In finding distance problems i understand the use of formula of d/rt then what i do not understand is the giving solutions in 3 decimal places. Can someone give an example step by step? The answer I do not need it is how to do it? Textbook says use calculator this is where problem is
Three decimal places is the three numbers after the decimal point.
Examples:
0.54675 = 0.547
0.41636 = 0.416
It is not d/rt, but d = rt, translating into distance = rate times time. This may be your problem.
.001 is three decimal places.
If you don't know how to use a calculator, do calculations by hand.
To solve distance problems using the formula d = rt, you may encounter situations where you need to round your answer to three decimal places. Here's a step-by-step example to help you understand the process:
Let's say you are given the following problem:
A car is traveling at a constant speed of 60 miles per hour. How far will it travel in 2.5 hours?
Step 1: Identify the given values:
- Speed (r) = 60 miles per hour
- Time (t) = 2.5 hours
Step 2: Substitute the given values into the formula: d = rt
- d = 60 * 2.5
Step 3: Perform the calculation:
- d = 150 miles
At this point, you have the exact answer of 150 miles. However, if you need to round it to three decimal places, continue to the next step.
Step 4: Use a calculator to round the answer:
- Enter 150 into your calculator.
- Press the decimal point button, usually represented as ".", to indicate that you want to round to three decimal places.
- The display should now show "150.000" or "150".
Note: Some calculators automatically round numbers to a certain number of decimal places, so it may not display trailing zeros. If this is the case, it's still considered correct.
In conclusion, if you're instructed to provide the answer rounded to three decimal places, the value of 150 miles would be written as "150.000" or simply "150".
