<h3>
m∠D = 80°</h3>
Step-by-step explanation:
In similar triangles corresponding angles have the same measure.
Lizette ran for 1.25 hours and walked for 3 hours.
distance = speed × time
Her total distance is the sum of her distances at the different speeds. Let w represent her walking speed in mi/h. For distances in miles, speeds in miles per hour, and time in hours, the problem statement tells us ...
19 = (w+5)(1.25) + (w)(3)
19 = 4.25w + 6.25 . . . . collect terms
12.75 = 4.25w . . . . . . . subtract 6.25
3 = w . . . . . . . . . . . . . . . divide by 4.25
Lizette's walking speed is 3 mph.
Lizette's running speed is 8 mph.
What you need to do it multiply the gallons in your car with the miles per gallon to see how many miles you can travel. So 8x30 is 240 miles so you need to make up 170 mpg. So you divide 170 by 30, so you would need about 5.6 gallons to complete your 400 mile trip
