How much money must stemmer invest if he wants to buy a bicycle in cash after 5 years? The bank offers him an interest rate of 8.8% compounded yearly. He needs R6600 at the end of the period to buy the bicycle.

4,329

Step-by-step explanation:

The computation of the amount invested is shown below:

As we know that

Present value = Future value ÷ (1 + interest rate)^years

= 6600 ÷ (1 + 0.088)^5

= 6600 ÷ 1.088^5

= 4,329

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
