​

he left home at 10 am

he rested two times

he travled 80 km

he travled 160 km total

he returned home at 9 pm

he was traveling at 26.67 km/hr while returning home

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
