Help with part b pls thank u

Vlad1618 [11]

Answer:

See below

Step-by-step explanation:

speed = distance / time
time = distance / speed

Time taken at the first part:

105 / x

ii)

Time taken at the second part:

(190 - 105) / (x + 12) =
85/(x + 12)

If time is 3 hours and 15 minutes = 3 1/4 hours = 13/4 hours, the equation is:

105/x + 85/(x + 12) = 13/4
4(x + 12)*105 + 4(85x) = 13x(x + 12)
13x² - 604x - 5040 = 0

Solve the equation:

13x² - 604x - 5040 = 0
x = [604 ± √((-604)² + 4*13*5040) ]/26 =
[604 ± √626896]/26 =
[604 ± 791.77]/26
x = (604 + 791.77)/26 = 53.68 km/h (taking positive root only)

105/x = 105/53.68 h = 1.956 h = 1 h 0.956*60 min = 1 h 57 min (rounded)
85/(53.68 + 12) = 85/65.68 = 1.294 h = 1 h 0.294*60 min = 1 h 18 min (rounded)

What is equivalent to 24/16

gulaghasi [49]

We can convert 24/16 to a mixed number. It will be equivalent to 24/16.

24/16
24 ÷ 16 = 1.5
16 can go in to 24 once.
24 - 16 = 8

1 = whole number
8 = numerator
16 = denominator

Lets write our mixed number:-

$1 \frac{8}{16}$

This can be simplified ^^^^

$\frac{8/8}{16/8} = \frac{1}{2}$

So, our old mixed number simplified is $1 \frac{1}{2}$

So, 24/16 is equivalent to 1. $1 \frac{8}{16}$ , 2. $1 \frac{1}{2}$

Hope I helped ya!!! xD
