Suppose you are walking home after school. The distance from your home to school is 5 km. on foot, you can get home in 1/2 mins. However, if you rode a bike, you could get home in 1/4 hour. what is your avereage speed on foot? What is your average speed on the bike? Show your work for each problem​

speed is distance over time.so you convert 1/2 to hours then solve

Step-by-step explanation:

hope it helped

1. a^4+8a^3+24a^2+32a+16

2.y^8+8y^7+28y^6+56y^5+70y^4+56y^3+28y^2+8y+1

3.x^6-3x^4y^2+3x^2y^4-y^6

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q
