Dr. Hall that is exploratory scouts travel 32 miles in eight hours the next day they had traveled 49 miles so they increase the speed by 3 mph how long did it take them to travel the 49 miles

it took them 7 hours to travel 49 miles.

Step-by-step explanation:

The exploratory scouts travel 32 miles in eight hours.

Speed = distance/time

It means that the speed at which they travelled 32 miles is

32/8 = 4 miles per hour.

The next day they had traveled 49 miles so they increase the speed by 3 mph. It means that the speed at which they travelled 49 miles is

4 + 3 = 7 mph

Time = distance/speed

Therefore, the time it took them to travel the 49 miles is

49/7 = 7 hours

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
