The probability that the teacher selects both boys from a seventh grader and eighth grader.
first calculate the probility that it is boy in each grade
7th
x = 7 / ( 7 + 3) = 7 / 10
8th
y = 2 / (2 + 2) = 1 / 2
so the probability
P = ( 7 / 10 ) ( 1 / 2 )
P = 0.35

Add the two trips together for total Km’s:
4500 + 11700 = 16,200 km.
divide total km by speed:
16,200 / 1,100 = 14.727272 hours
0.727272 x 60 minutes per hour = 43.636363 minutes, round up to 44 minutes
total time: 14 hours and 44 minutes
