amelia is riding in a hot-air balloon traveling at a speed of about 8 miles per hour. at this speed, about how many miles will the balloon have traveled after 1.25 hours?
a. 6.4
b. 7.75
c. 9.25
d. 10.0

C.

I think because in 1 hour (60 min) she flew 8 miles + 0.25 of an hour (15 min) 8 / 4 = 2

2 miles per 20 min

take the 1 hour which is 8 miles

then the 15 min

1.25

     1.25

  + 8.00

     9.25

D

Step-by-step explanation:

If she is going at 8 MPH the whole time and she traveled for 1.25 hours

8 MPH means 8 miles in 1 hour so

1 Hour = 8 Miles

0.25 Hours = 2 Miles

0.25 is 1/4 of 1 which means its 4 times smaller and 8 divided by 4 = 2

8+2=10

The answer is D. 10

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
