Answer:
They will reach after 26 hours i.e tomorrow noon
Step-by-step explanation:
Start time = 10 a.m
Starting point marker = 2 mile
End point = 80 miles
Distance to be traveled = 80 - 2 = 78 miles
Average speed = 3 miles per hour
Now,
Time = [tex]\frac{\textup{Distance}}{\textup{Speed}}[/tex]
or
Time = [tex]\frac{78}{3}[/tex]
or
Time = 26 hours
Therefore,
They will reach after 26 hours i.e tomorrow noon
