1.) Let their speed be x, then distance travelled = speed x time
1.5x + 2.5x = 240
4x = 240
x = 240/4 = 60
Their speed is 60 miles per hour.
2.) Let catie's brother's age be x, then catie's age is 3 + x
x + 3 + x ≤ 31
Required inequality is 2x + 3 ≤ 31
2x ≤ 31 - 3
2x ≤ 28
x ≤ 28/2
x ≤ 14
Therefore, the oldest age Catie's brother can be is 14 years old.
3.) Let June's age be x, then her father's age is 6x
6x + x ≥ 77
7x ≥ 77
x ≥ 77/7
x ≥ 11
The youngest age Julio can be is 11 years old.

Answer:
4524.9
Step-by-step explanation:
<u>Area of a parallelogram:</u>
A = bh
A = 63 x 90
A = 5670
<u>Area of half-circle:</u>
A = (πr²)/2
A = (π x 27²)/2
A = (π x 729)/2
A = 729/2π
<u>Combined:</u>
5670 - 729/2π
4524.9
