Answer:
6/25 km in 1 min; or 0.24 km/min
Step-by-step explanation:
The info about Angel is not necessary.
Jayden runs 3 laps in 5 mins
Each lap is 2/5 km, so Jayden runs 3 x (2/5 km) in 5 min = 6/5 km in 5 min.
Distance = rate x time
6/5 km = rate (5 min)
We want to isolate r (rate), so divide both sides by 5 min 
6/5 km ÷ 5 min = r
6/5 km (1/5 min) = r
6/25 km/min = r  (notice how the units worked out correctly to km/min)
So, Jayden runs 6/25 km in 1 min.

Answer:
7) 10^(3/2)
8) 2^(1/6)
9) 2^(5/4)
10) 5^(5/4)
Step-by-step explanation:
7)  (√10)^3 = 10^(3/2)
8)  6 root 2 = 2^(1/6) 
9)  (4 root 2)^5 = 2^(5/4)
10) (4 root 5)^5 = 5^(5/4)
 
        
             
        
        
        
The answer is -8/15 because you need to cancel out the variables first
