(a) Jason arrives at the factory first
(b) It takes 5 minutes until the other person arrives
Step-by-step explanation:
Jason and Jeremy work together at a juggling-ball factory
- Jason lives 25 miles away from the factory and drives at 60 miles per hour
- Jeremy lives 35 miles away from the factory and drives at 70 miles per hour
- They leave their houses at the same time
We need to know who arrives at the factory first and how long it is until the other person arrives
Time = Distance ÷ speed
∵ Jason lives 25 miles away from the factory
∴ The distance = 25 miles
∵ He drives at 60 miles per hour
∴ The speed = 60 miles per hour
- Use the rule above to find the time
∵ Time = 25 ÷ 60 = hour
∵ 1 hour = 60 minutes
∴ hour =
∴ Jason arrives to the factory in 25 minutes
∵ Jeremy lives 35 miles away from the factory
∴ The distance = 35 miles
∵ He drives at 70 miles per hour
∴ The speed = 60 miles per hour
- Use the rule above to find the time
∵ Time = 35 ÷ 70 = hour
∵ hour =
∴ Jeremy arrives to the factory in 30 minutes
∵ They leave their houses at the same time
∵ 25 minutes < 30 minutes
∴ Jason arrives first
(a) Jason arrives at the factory first
∵ Jason arrives to the factory in 25 minutes
∵ Jeremy arrives to the factory in 30 minutes
∵ 30 - 25 = 5 minutes
∴ Jeremy arrives after Jason by 5 minutes
(b) It takes 5 minutes until the other person arrives

Answer:
Other Side (B) = 9.45 inches
Step-by-step explanation:
Given:
Hypotenuse = 10 inches
Other Side (A) = 3.25 inches
Find:
Other Side (B) = ?
Computation:
According to Pythagoras theorem:
Other Side (B) = 9.45 inches
Check the picture below.
so then γ ≈ 180 - 69 - 43, γ ≈ 68.
