Jessie loves to go hiking on rustic trails through trees and along rivers.One day in 20 minutes of hiking, she hiked 1 mile. If
Jessie hiked at a constant rate, what would that rate be?Write Jessie's hiking rate in all the ways you can think of from the information given. *
1 answer:
Answer:
Jessie hiked at a constant rate of 3 miles/hour
Step-by-step explanation:
Constant rate can also be called speed
The formula for constant rate /Speed = Distance (miles)/ time in hours
Distance = 1 mile
Time = 20 minutes
Converting to hours
60 minutes = 1 hour
20 minutes =
20/60
= 0.3333333333hour
Constant rate = 1mile/0.3333333333 hour
= 3.0000000003
= 3 miles/hour

X + y = -3 . . . (1)
y = 2x + 2 . . . (2)
substituting (2) into (1) gives, x + 2x + 2 = -3
3x = -5
x = -5/3
From (2), 2(-5/3) + 2 = -10/3 + 2 = -4/3
Required solution (-5/3, -4/3)
cosx = 3/5
sin²x + cos²x = 1
sin²x = 1- 9/25
sin²x= 16/25
sinx = 4/5
tanx = sinx/cosx
tanx = 4/3
