Agroup of hikers walked 2 1/4 km in 3/4 hour. c on a coordinate plane, plot the four points showing distance hikers went in ¾ of an hour, 2 hours, 3 hours, 4 hours

Given,

The total distance = km,

Time = hours,

Since,

Thus, the speed of the group of hikers =

= 3 km per hour,

Now, Distance = speed × time

Let y be the distance( in km ) covered in x hours  

⇒ y = 3x

If x =

If x = 2

If x =3

If x = 4

Hence, the required points in the coordinate plane are, ( shown in the below diagram )

(3/4, 9/4), (2, 6), (3, 9) and (4, 12)

25/6

step-by-step explanation:

you multiply 4 by the denominator (4*6=24) and add it to the numerator which makes it 25/6.

using pemdas, (order of operations) you'll see the answer is 24.
