1.	A bus travels with speed of 54km/h time 2 hours and 32 km/hour time 1 hour what is average speed of bus.
Answer» ANSWER: $\frac{140}{3} \frac{km}{h}$ EXPLANATION: $With \: the \: speed \: 54 \frac{km}{h \: } \: distance \\ travelled \: by \: bus = (54 \times 2)km = 108km \\ \\ With \: the \: speed \: 32 \frac{km}{h } \: distance \: \\ travelled \: by \: bus = (32 \times 1)km = 32km \\ \\ Average \: Speed \: = \frac{total \:distance \: travelled }{total \: time \: taken} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{(108 + 32)km}{(2 + 1)h} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{140km}{3h} \\ \\ \\ hope \: it \: will \: help \: you..$

A bus travels with speed of 54km/h time 2 hours and 32 km/hour time 1 hour what is average speed of bus.

Answer»

$\frac{140}{3} \frac{km}{h}$

$With \: the \: speed \: 54 \frac{km}{h \: } \: distance \\ travelled \: by \: bus = (54 \times 2)km = 108km \\ \\ With \: the \: speed \: 32 \frac{km}{h } \: distance \: \\ travelled \: by \: bus = (32 \times 1)km = 32km \\ \\ Average \: Speed \: = \frac{total \:distance \: travelled }{total \: time \: taken} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{(108 + 32)km}{(2 + 1)h} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \frac{140km}{3h} \\ \\ \\ hope \: it \: will \: help \: you..$
