11.66 or 12
Step-by-step explanation:
c^2 = a^2 + b^2
19^2 = 15^2 + b^2
361 = 225 + b^2
361 - 225 = b^2
136 = b^2
(square root of both sides)
b = 11.66or 12
Answer: 3km/h
Step-by-step explanation:
Johns average speed was 6km/h, so in 3 hours he traveled 18 km. 27-18=9, so Peter ran 9 km in 3 hours. 9/3 = 3, so his average speed was 3km/h
200/19.30 is the problem, the solution is 10.3626943 and if you round that it is 10.26. I hope this helps you!
