The correct answer is D). y=x/2+10
Step-by-step explanation:
In normal days, Jade leaves the office at 5 pm and take " Street road " to go home in time " x ". so that, Jade will be at home around 5 pm, x mins
Today, Jade leave the office 10 mins late and take " toll road " instead of " street road.
It is said that " Jade travel two times faster on toll road than the street road "
That means Jade will take 1/2th time than normal days i.e. x/2
We need to make the equation of time taken by Jade to reach home after 5 pm.
Let say, the total time (after 5 pm ) is "y"
Bring all things together,
Statement 1: Jade will take 1/2th time than normal days i.e. x/2
we can write, y=x/2
Statement 2: Jade leave the office 10 mins late
Jade is late by 10mins so, we will add that time
y=x/2+10
So that, today Jade will be at home around 5 pm, x/2+10 mins
The correct answer is D). y=x/2+10
