Juan and his family fly from London to Rio de Janeiro. The plane departs at 10 20 and arrives in Rio de Janeiro 11 hours 40 minutes later.
The local time in Rio de Janeiro is 5 hours behind the local time in London.
Work out the time in Rio de Janeiro when the plane arrives.​

The time in Rio de Janeiro when the plane arrives is 17:00.

Step-by-step explanation:

Since Juan and his family fly from London to Rio de Janeiro, the plane departs at 10:20 and arrives in Rio de Janeiro 11 hours 40 minutes later, and the local time in Rio de Janeiro is 5 hours behind the local time in London To work out the time in Rio de Janeiro when the plane arrives, the following calculation must be performed:

(10:20 + 11:40) - 05:00 = X

22:00 - 05: 00 = X

17:00 = X

Thus, the time in Rio de Janeiro when the plane arrives is 17:00.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
