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
The problem arises with establishing whether the children have a problem because of some sort of disability or simply because they are not proficient enough in English. When a child has a problem communicating that could indicate that child possesses some kind of disability that would need to be addressed. But with linguistically-diverse children the problem to communicate might come from the their knowledge of English which can be inadequate so the to educators need to be careful not to wrongly deal with these kind of children.
