Matching each formula to its correct description yields the following;
- 1. simple interest I = prt
- simple interest I = prt 2. distance d = rt
- simple interest I = prt 2. distance d = rt3. time money is invested t = I/pr
- simple interest I = prt 2. distance d = rt3. time money is invested t = I/pr4. rate of speed r = d/t
- simple interest I = prt 2. distance d = rt3. time money is invested t = I/pr4. rate of speed r = d/t5. rate of interest t = I/pt
- simple interest I = prt 2. distance d = rt3. time money is invested t = I/pr4. rate of speed r = d/t5. rate of interest t = I/pt6. time spent driving t = d/r
According to the question;
- We are required to match each formula to its correct description.
The simple key is that;
For Simple interest; the formula is;
- I = prt where;
- I = simple interest
- p = amount invested
- r = rate of interest
- t = time money is invested
For rate of speed; the formula is;
- r = d/t where;
- r = rate of speed
- d = distance
- t = time spent driving.
The subject of each formula can be changed to suit the required quantity.
