\( 1+6+11+16+.....+56= \)

Evaluate the absolute value of \( -8 \).

The distance between two towns is 90 km . A bus driver averages \( 30 \mathrm{~km} / \mathrm{h} \) in heavy traffic in one direction and \( 45 \mathrm{~km} / \mathrm{h} \) on the return trip. Calculate the total time taken and the average speed for the total journey. \( 5 \mathrm{hours}, 36 \mathrm{~km} / \mathrm{h} \)

Round \( 5.34 \) to the nearest tenth.
