Total distance = 200 miles
Time needed for the first 100 miles
= 100 ÷ 40 = 2.5 hours
Time needed for the second 100 miles
= 100 ÷ 50 = 2 hours
Total time = 2.5 + 2 = 4.5 hours
Average speed = 200 ÷ 4.5 hours = 44.4 miles per hour

Answer:
54.91
Step-by-step explanation:
64.6/x=100/85

54.91=x
x=54.91
now we have 85% of 64.6= 54.91
I am pretty sure it’s y=1
