Two motorcyclists start at the same point and travel in opposite directions. One travel 3 mph faster than the other. In two hours they are 206 miles apart. How fast is each traveling?
The speed of the slower motorcyclist is ___ mph.
speed of slower ---- x mph
speed of faster ---- x+3 mph
after 2 hours:
distance covered by slower = 2x
distance covered by faster = 2(x+3)
2x + 2(x+3) = 206
so is the answer 50
You tell me .
Does that answer work for the original conditions?
i think so but the answer suppose to be in the form of x and y
Are you looking at the answers to this question?
There is no need for two variables
I defined x to be the slower speed, and x = 50
I defined x+3 to be the faster speed, or x+3 = 53
distance covered by slower in 2 hours = 2(50) = 100 miles
distance covered by faster in 2 hours = 2(53) = 106
and what is 100+106 ? ...
looks good to me.
so what is the speed of the slower biker ?
