he drove an average of 50 mph for 6 h for the 1st 4 hours he drove 47 mph what was his speed for the ast 2 hours

total distance: 50*6 = 300

distance @ 47mph: 4*47 = 188
300-188 = 112 miles in 2 hrs = 56 mph

6x+2/3x+3 division sign 2x-2/4x+4

divide 50 by 6 and times the answer with 2

To find the speed for the last 2 hours, we can subtract the distance covered in the first 4 hours from the total distance covered in 6 hours.

Let's calculate the distances traveled in the first 4 hours and the overall distance:

Distance traveled in the first 4 hours:
Speed = 47 mph
Time = 4 hours
Distance = Speed * Time = 47 mph * 4 hours = 188 miles

Total distance:
Speed = 50 mph
Time = 6 hours
Distance = Speed * Time = 50 mph * 6 hours = 300 miles

Now, let's find the distance covered in the last 2 hours:

Distance covered in the last 2 hours = Total distance - Distance covered in the first 4 hours
= 300 miles - 188 miles
= 112 miles

To find the speed for the last 2 hours, divide the distance covered in the last 2 hours by the time taken:

Speed for the last 2 hours = Distance / Time = 112 miles / 2 hours = 56 mph

Therefore, his speed for the last 2 hours was 56 mph.
