HELP

Step-by-step explanation:

Speed = Distance / Time

If we measure distance in miles and time in hour, we will get the speed in miles per hour.

Distance = 1 + 2/3 miles, which expressed as an improper fraction is 5/3 miles.

Time = 50 minutes which expressed in hours will be 50/60 or 5/6 hours.

(You can also see that 10 minutes is 1/6 of an hour, hence 50 minutes is 5/6 of an hour)

Speed = Distance / Time

         = (5/3) / (5/6)

We know that dividing by "a/b" is same as multiplying by "b/a"

Hence, we have:

Speed = (5/3) * (6/5)

         = (5 * 6) / (3 * 5)

         = 30 / 15

         = 2

Mara walks at a speed of 2 miles per hour

2 miles per hour

Step-by-step explanation:

To find her walking pace in 'miles per hour' we need to divide the distance (in miles) by the time (in hours).

Speed = Distance/ Time

The time is given in minutes , but 50 minutes = 50/60 hours

=5/6 hours

1 2/3 ÷ 5/6

=5/3 × 6/5 miles per hour

Now cut it

= 2 miles per hour

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
