Answer: 3 : 1

Step-by-step explanation:

We know that the ratio of A to B is given by :-

\dfrac{A}{B} or A : B .

Given : Number of students having brown hair = 15

Number of students having black hair = 5

Then , the ratio of students with brown hair to students with black hair will be  :-

=\dfrac{\text{No. of students with brown hair}}{\text{No. of students with black hair}}\\\\=\dfrac{15}{5}=\dfrac{3}{1}

Hence, the ratio of students with brown hair to students with black hair = 3 : 1.

A bus travels at a constant speed. The following table shows the distance the bus travels (in kilometers) over a period of time
Olegator [25]

Answer:

315 km

Step-by-step explanation:

If the bus travels at constant speed, then the slope of the distance versus time graph can be calculated by using any two points from this table.

Let's use the points (0.5, 42) and (4.5, 378):

as we move from the first point to the second, t increases by 4 and y increases by 336.  Thus, the slope of this graph is

m = rise / run = 336 km  /  4 hr  =  84 km/hr

then distance traveled = speed times time, or

distance traveled = (84 km/hr)t, where t is the elapsed time.

In 6 hours the bus would travel

                                 ( 84 km/hr )(6 hr) = 504 km, or approx. 315 mi
