You have to make proportions
65mi/1h=125mi/xhours
you end up with 65x=125
125/65=1.92hours--> round it to 2 hours
it takes 2 hours
What do you mean by that i mean yeah you can have as many as needed to subtract
Answer:
Step-by-step explanation:
let speed of Stephen=x mph
speed of Diana=x+4
then
6x+6(x+4)=276
divide by 6
x+x+4=276/6=46
2x=46-4=42
x=42/2=21
Stephen is traveling at 21 mph.
Diana is traveling at 21+4=25 mph.
Answer:
width = 8 ft & length = 32 ft.
Step-by-step explanation:
let the width be x and length be 4x.
we know, Perimeter = 2(l+b)
now,
2(4x + x) = 80
10x = 80
x = 80/10 = 8
x = 8
therefore,
width = x = 8 ft
length = 4x = 4 × 8 = 32 ft.
hope this helps you !
