Answer:
80 and 90 mph
Step-by-step explanation:
Given that A and B have a distance of 1029 miles between them. Two trains each start from A and B and move towards each other.
Let the speed of I train be s
Then speed of second train = s+10 (since 10 greater than speed of I train)
Relative speed = s+s+10 = 2s+10
In 5 hours they travelled together a distance of 1020-170 =850 miles
Distance travelled = 850 miles
Relative speed = 2s+10
Time taken = 5 hours
Since distance = time x speed
we have
5(2s+10) =850
2s+10 =170
s = 80
Speed of the trains are 80mph and 90 mph
I find it easier to put them in decimal form then to try and find a common denominator
2/3 = 0.666
2/9 = 0.222
5/6 = 0.833
11/18 = 0.611
least to greatest = 2/9, 11/18, 2/3, 5/6
