3of 6 ryan and mary are both travelling by train. ryan's train travels 80 km in 50 minutes. mary's train travels 270 km. it leaves at 13: 10 and arrives at 15: 25. work out the difference, in km/h, between the average speed of their trains. km/h

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
