Step-by-step explanation:
y-y₁=m(x-x₁)
1-(-4)=m(4-3)
5=m
Answer:
18/5 miles
Step-by-step explanation:
let d be the mountain dist path
upward biking
x miles - 1 hr
d 45 mins
3x/4 = d
riding down
x+3 - 60 min
d. - 20
(1/3)(x+3) = d
(x+3)/3 = 3x/4
4x+12 = 9x
x = 12/5
d =( 12*3)/(4*5)= 9/5
upward+downward = 2*(9/5) = 18/5
Since 1 lap I every 6 minutes then 30\6 is 5 so the answer is 5 LAPS
7712 divided by 32
= 7712/32= 241
First divide by 2 to give
3856/16
Divide again by 2 =
1928/8 and again by 2
964/4 and again by 2 to give
482/2 and divide by 2 again to give 241
