Answer 1

Sol)
$distnce \: travelled \: = \: 150km \\ \: \: \: \: \: \: \: speed \: = 60km \\ time = distance \div speed \\ \: \: \: \: \: \: \: \: \: \: time = \: 150 \div 60 \\ \: \: \: \: \ \: \: \: \: \: \: = 2.5hrs (2hrs and 30minutes) \\ \\ but \: total \: time \: taken \: = 2hrs 30minutes + 45minutes \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3hrs15minutes \\ therfore \: \: he \: reachs \: \: at \: 2 : 45pm$
