The fraction is 4 1/2. Just convert the decimal into a fraction. 50/100 is the same as 5/10 which is the same as 1/2.

Because 4 is in front of the decimal point that is the whole number and five is behind the decimal point so you have to put it over ten. the answer is 4 and 5/10 but can be reduced to 4 and 1/2

Does anyone know these answers please help

1) this is simply solving it, so if you divide 16 by 3, you end up getting 5 1/3

2) 3 1/2, by multiplying 7 by 1/2

3) 224, by multiplying 14 by 16

4) 54 mph, by dividing 324 by 6

5) blue, because only the 1/4 ribbon color would be collected after 3/4 mile

6) 7/8 - 3/8 equals 4/8, or 1/2 when simplified

Jane spent 3 hours exploring a mountain with a dirt bike. First, she rode 55 miles uphill. After she reached the peak she rode f
Neko [114]

Answer:

Her speed on the summit was 35 mph.

Step-by-step explanation:

Her speed on the summit was "x" mph while her speed while climbing was "x - 10" mph. The distance she rode uphill was 55 miles and on the summit it was 28 miles. The total time she explored the mountain was 3 hours. Therefore:

time uphill = distance uphill / speed uphill = 55 / (x - 10)

time summit = distance summit / speed summit = 28 / x

total time = time uphill + time summit

3 = [55 / (x - 10)] + 28 / x

3 = [55*x + 28*(x - 10)]/[x*(x - 10)]

3*x*(x - 10) = 55*x + 28*x - 280

3x² - 30*x = 83*x - 280

3x²  - 113*x + 280 = 0

x1 = {-(-113) + sqrt[(-113)² - 4*(3)*(280)]}/(2*3) = 35 mph

x2 = {-(-113) - sqrt[(-113)² - 4*(3)*(280)]}/(2*3) = 2.67 mph

Since her speed on the uphill couldn't be negative the speed on the summit can only be 35 mph.
