Adam's average speed = 40 miles per hr
time for the trip = 30 minutes = 0.5 hrs
Distance travelled by adam = speed * time = 40 * 0.5 = 20 miles
Distance travelled by Beth is 5 miles longer means 20 + 5 = 25 miles
Time took by Beth is 20 minutes more means = 30 + 20 = 50 minutes = 0.83 hrs
Average speed of Beth = distance / time = 25 / 0.8333
Average speed of Beth = 30 miles : Answer
Hope it will help :)

To check my work I used desmos
Second one EGF to KJI
EG/IG =GF/JK=FE/KI
90/120 =135/180=117/156
0.75=0.75=0.75

Sort the numbers from least to greatest and find the middle number (that should be your median)
If there are 2 numbers in the middle of the set, then you take the average and that would be your median.
