Answer is B
How I got is because I had to first figure out what 40 seconds worth of heartbeats are equal to. 80 - 48 is 32 divided by 2 is 16. Next, I added 48 and 16 which got me 64. All I had to do next was to add 80 and 16 because the rate of heartbeats per 10 seconds is 16. 80+16=96 and thats how I figured that the answer is B
Let's write f(x)=4x-1, g(x)=-3x+5
We see f(.8)=2.2, g(.8)=2.6 close, with g a bit bigger
then f(.9)=2.6, g(.9)=2.3 also close, with f a bit bigger
We see f and g crossed somewhere between .8 and .9 at a value beween 2.2 and 2.6, so I'd guess a meet near (0.85, 2.4). Closest answer is
Answer: D (.9, 2.4)
