Question

A football match being played at Sao Paulo, Brazil started in India at 6 am IST. Explain what would be the local time at Sao Paulo

Answer 1

-First of all you need to get the time difference of the two geographical positions.

$Step1$

-To get this you need to know the longitudes of the two places on the map.

India New Delhi=77°22E

Sao Paulo ,Brazil=46°63W

$Step2$

-Since the two geographical positions are not on the same side (East or West) you add the two values Of the longitudes. If they were on Similar sides then you subtract the Longitudinal values.

77°22+46°63

Answer= 123°85

$Step3$

-To convert the degrees to minutes you use the formula

1°=4 minutes

then

if 1°=4 minutes what about 128.85°

1°=4 minutes

123.85°= ?

Then you cross multiply to be

123.85×4

Answer=495.4 minutes

$Step4$

-You separate the fraction and the whole number and the fraction part

Divide the whole number part by 60 to change the minutes to hours

495÷60

Answer= 8.25(8 hours 15 minutes)

Then now change the fraction part into minutes by dividing by 60 seconds to change to minutes.

0.4(2/5)÷60

Answer=0.006666666 minutes

$NB:$ This value will be assumed because Minutes together with hours can only be include with 2significant figures

$Step5$

-Finally when To get the time in Sao Paulo you subtract The time difference from the IST time in India because india is in the East hence it receives Light earlier than Sao Paulo which is in the west .

6:00am(add 12 in oder to subtract)

hence

18:00-8:15

=9:45pm
