Average speed = (distance covered in some time) / (time to cover the distance)
4 hours 45 minutes = 4-3/4 hours = 4.75 hours
Average speed = (3,800 km) / (4.75 hours) = 800 km/hr

C. 1 1/3
7/9 + 5/9 = 12/9
12/9 = 1 3/9 = 1 1/3
4x-6= 22
Move -6 to the other side.
Sign changes from -6 to +6.
4x-6+6= 22+6
4x= 22+6
4x= 28
Divide by 4 for both sides
4x/4= 28/4
x= 7
Answer : x= 7
