Match each formula to its correct description.
1. simple interest i = prt
2. distance r = d/t
3. time money is invested r = l/pt
4. rate of speed t = i/pt
5. rate of interest t = d/r
6. time spent driving d = rt

Respuesta :

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.
