Answer:
465 miles
Step-by-step explanation:
From the question,
S₁ = d₁/t₁............................... Equation 1
Where S₁ = Speed travels by Perry for the first journey, d₁= First distance traveled by Perry, t₁ = First time taken.
make d₁ the subject of the equation
d₁ = S₁t₁................... Equation 2
Given; S₁ = 55 miles per hour, t₁ = 5.5 hour
Substitute these values into equation 2
d₁ = 55×5.5
d₁ = 302.5 miles.
Also,
d₂ = s₂t₂.......................... Equation 2
Given: s₂ = 65 miles per hour, t₂ = 2.5 hours.
d₂ = 65×2.5
d₂ = 162.5 miles
Hence,
Total distance = d₁+d₂
Total distance = 302.5+162.5
Total disstance = 465 miles

Step-by-step explanation:
Answer:
P = 18.4 units
Step-by-step explanation:
Sides AB and CD are congruent and thus have the same length.
Sides AD and BC are congruent.
The length of side AB is found using the Pythagorean Theorem:
|AB| = √ [ 5² + 1² ] = √26
and
|BC| = √ [ 4² + 1² ] = √17
Then the perimeter is P = 2(√26) + 2(√17), or
10.20 + 8.25, or, to the nearest tenth,
P = 18.4 units
