Answer:
24,150km
Step-by-step explanation:
The plane travels 3450km in 1 hr, since we need the distance traveled in 7 hrs we need to multiply 3450 by 7.
distance in 7hrs: 3450*7 = 24,150km
Answer:
44m
Step-by-step explanation:
area of a trapezoid = (a+b)* h/2
since the distance between two parallel sides is 15, that would be your height
plug everything in and you get:
480 = (20 + b) *15/2
b = 44
Since is addition you do the opposite and subtract 12 from 12 and -5 then 12 cancels out and -5-12=-17
