Let the speed at which John is going towards Leakey = x mph
Time taken to reach Leakey = 4 hours
Distance = speed * time
So let the distance of Leakey from John's house be 4x ............. (1)
Speed while returning was 20 mph less = (x-20)
Time taken was= 7 hours
distance = (x-20)*7 ................(2)
As the distance remains the same, equation 1 = equation 2
So, the speed is mph
Distance = 4x
=
Hence, the distance of Leakey from John's house is 186.667 miles.
Answer:
Step-by-step explanation:
In order to find the Perimeter, we add all the segments up.
(2x-1)+(4x+3)+(x+2)+(2x+2)+(1/10x-1)+(2/5x)
=2x-1+4x+3+x+2+2x+2+1/10x-1+2/5x ⇔ Expand Parenthesis
=2x-1+4x+3+x+2+2x+2+1/10x-1+4/10x ⇔ Convert fractions into same
denominator
=(2x+4x+x+2x+1/0x+4/10x)+(3-1+2+2-1) ⇔ Put like terms together
=(9x+1/2x)+5 ⇔ Combine like terms
=9 1/2 x +5
Hope this helps!! :)
