Answer: Adam's average speed is 33 mph.
Step-by-step explanation:
Let x represent Adam's average speed.
By the time Maria catches up with Adam, they would have covered the same distance.
Distance = speed × time
Distance travelled by Adam after 4 hours is
4 × x = 4x
Maria left one hour later driving 11 km/h faster in an effort to catch up to him. This means that Maria's speed is (11 + x) mph and the time she spent travelling is 4 - 1 = 3 hours. Distance covered by Maria is
3(11 + x)
Since they covered the same distance, it means that
4x = 3(11 + x)
4x = 33 + 3x
4x - 3x = 33
x = 33 mph
Answer:
no solution
Step-by-step explanation:
10x-83-4x=6x
combine like terms
6x-83=6x
cross the equal sign
-83=0
aka no solution
