bashiru takes 4min 12second to run 1km. kunle takes only 4min. what is the ratio of bashiru's time to kunle's

21 : 20

Step-by-step explanation:

*Change the unit from minute into second first

bashiru:

4 minutes x 60 = 240 seconds

(Explanation: because 1 minute have 60 seconds, then 4 minutes= 4 x 60 seconds)

240 seconds + 12 seconds = 252 seconds

kunle:

4minutes x 60 = 240 seconds

bashiru : kunle

252 : 240 ‹Simplify (divide by 12)

21 : 20

Thus, the answer is 21:20

Hope this helps ^_^

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
