Answer:

90min

Step-by-step explanation:

we can solve the first part by means of the rule of three:

5.3miles ----2.5 hour

3.18miles----x

then

x=\frac{3.18*2.5}{5.3} \\x=\frac{7.95}{5.3} \\x=1.5 hours

Now we must convert hours to minutes:

1.5 hours = 1.5hours (1)

1.5 hours =1.5 hours \frac{60min}{1 hours}

1.5 hours =(1.5)(60) min

1,.5 hours =90min

Answer:

2.27%

Step-by-step explanation:

Lets start by making the names letters, J C and A respectively.

The total is 44 dollars. J paid 34%, which would be 14.96. He pays a total of $15. C paid 50%, which is 22 dollars. A pays 17%, which would be 7.48. She pays a total of $8.

15 + 8 + 22 = $45, meaning they paid an extra 1 dollar. One dollar is 1/44th of $44, or 2.27%.

Note: 2.27% is 2.272727272727 repeated, do what you will with that information, every site is different.
