02%3A50%2Bhighlight%28%2B24%3A00%29=26%3A50
The reason adding 24:00 to 02:50 is to make it subtractable by 19:25.
26%3A50-19.25=7%3A25
This subtraction has shown that the total time taken on the journey is 7 hours 25 minutes.
Q1
Time taken for the bus to take to its journey
=7+hours+25+minutes
=7+hours%2B25+minutes
=%287x60%29minutes%2B25+minutes
=445+minutes
Q2
Time taken for the bus to take to travel 1 kilometer
=%28%28445x60%29seconds%29%2F540
=%2826700+seconds%29%2F540
=49seconds
Q3
The average speed of the bus
=%28%287+hours+25+minutes%29%2F540km%29
=%28%287+hours%2B25+minutes%29%2F540km%29
=%287+hours%2B%2825%2F60%29hours%29%2F540km
=%28%287%2B25%2F60%29hours%29%2F540km
=%28%2889%2F12%29hours%29%2F540km
