Answer:
6⅓ hours (or 6 hours and 20 minutes)
Explanation:
For Khalil on foot;
Let;
Speed = x miles/hour
Time = 4 hours
Distance = D (miles)
Speed = distance/time
x = D/4
D = 4x miles
For Khalil on the bus;
The bus travels at 6 times his walking rate, therefore;
Speed = 6x miles/hour
Bus follows a route that is twice as long, therefore;
Distance = 2D (miles)
Time = T (hours)
Speed = distance/time
6x = 2D/T
Remember, from above, D = 4x
Therefore,
6x = 2(4x)/T
6x × T = 8x
T = 8x/6x
T = 4/3 hours = 1⅓ hours
Therefore time spent by khalil on the bus = 1⅓ hours or 1 hour, 20 minutes.
Total hours spent on entire trip = hours khalil spent walking + lunch hour + hours khalil spent on the bus
Total hours = 4 + 1 + 1⅓ = 6⅓ hours
