First we need to find out the time it took for the truck to reach town B.
Now, because the van left 1.5 hours earlier and reached the destination 2.5 hours before, it took 1 hour less the the truck to arrive.
which is the time it took for the van to arrive.
Now we use the speed equation again to work out speed.
= speed of van
Hope this helped :)

Answer: 225 square feet
Step-by-step explanation:
We find the area of the 4 triangle and the area of the rectangle and thereafter we add everything together.
Area of triangle 1 = 1/2 base × height
= 1/2 × 12 × 8
=96/2
=48
Area of triangle 2 = area of triangle 1= 48( because the opposite triangle are congruent so they have equal base and height)
Area of triangle 3 = 1/2×base×height
= 1/2 × 6 ×9.5
= 57/2
=28.5
Area of triangle 4=Area of triangle 3 = 57 (the opposite triangle are congruent and so they have the same base and height hence the same area)
Area of the rectangle = length×breadth
=12 × 6 =72
Total surface area = addition of all the areas of the triangles and the rectangle
Total surface area= 48+48+57+57+72 = 225
Therefore, the total surface area is 225 square feet
Answer:
x = 5
AB = 26
BC = 39
Step-by-step explanation:
A___B___C
AC = AB + BC
65 = (5x+1) + ( 7x+4 )
65 = 12x + 5
12x = 65-5
12x = 60
x = 60/12
x = 5
AB = 5x +1 = 5(5) +1 = 25 +1 = 26
BC = 7x+4=7(5) + 4 = 35 +4 = 39
I hope I helped you^_^
