Joy made a deposit of $1600 into an account with a rate of 5%. How long should she leave the money into the account if she wants to earn $240 in interest

3 years

Step-by-step explanation:

The following can be gotten from the question:

Principal = $1600

Rate = 5%

Simple interest = $240

Time = Unknown

Interest = Principal × Rate × Time /100

240 = (1600 × 5 × Time)/100

240 = (8000 × Time)/100

240 × 100 = 8000 × Time

24000 = 8000 × Time

Time = 24000/8000

Time = 3 years

goog may be able to you find that answer

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
