Answer:
28mph
Step-by-step explanation:
Let the speed at which Pat drives be xmph.
Now, we know John travels 32mph faster than Pat. Hence, John's speed is (x + 32)mph
The total distance is 440 miles.
Distance = Speed × Time
The distance traveled by each of them after 5 hours is given as follws;
Pat = 5 × x = 5x miles
John = 5(x + 32) miles
Now, if we add both distances, we get the total of 440 miles.
Hence, 5x + 5(x + 32) = 440
5x + 5x + 160 = 440
10x + 160 = 440
10x = 440 - 160 = 280
10x = 280
Hence, x = 280/10 = 28mph
The median is the number in the middle...so write your frequencies out, in least to greatest and find the one that falls in the middle.
