The formula for average speed is: \large \color{#EC7300} \text{The formula for average speed is:}

A v e r a g e s p e e d = t o t a l d i s t a n c e t o t a l t i m e \large \color{#3D99F6} Average\ speed = \frac{total\ distance}{total\ time}

Therefore: [Note that total time is given in hours to 24 x 276 = 6624 h] \large \color{#EC7300} \text{Therefore: [Note that total time is given in hours to 24 x 276 = 6624 h]}

= 34560 k m 6624 h \large \color{#20A900} = \frac{34 560\ km}{6624\ h}

= 5.2 k m p e r h o u r \large \color{#20A900} = 5.2\ km\ per\ hour
