A set of equation can be set up:
a=b+15
3(a+b)=345
where a is the faster and b is the slower bus.
substitute b+15 into the second equation, so 6b+45=345, and 6b=300, therefore b=50.
we can then figure out that a=65

Answer:
D
Step-by-step explanation:
If you mean the sqrt of 43, then
sqrt 36 is 6
sqrt 49 is 7,
since sqrt of 43 is between sqrt 36 and sqrt 49,
sqrt of 43 is between 6 and 7
