We have that, how long it will take for Liu to catch Mariel is mathematically given as

t=3.076s

From the question we are told

Mariel and Liu are running a long-distance race. Mariel runs at a rate of 5.4 m/s, and Liu runs at a rate of 7.6 m/s. If Mariel has a 20 m head start, how long will it take for Liu to catch Mariel?

Generally the equation for the Average speed is  mathematically given as

v_a=\frac{5.4+7.6}{2}\\\\V_a=6.5m/s

Therefore

How long it will take for Liu to catch Mariel is mathematically given as

t=\frac{20}{6.5}

t=3.076s

Which is true about the volume or surface area of these prisms?
GrogVix [38]
The correct answer is B- The surface area of B is greater than the surface area of A. I got this answer because...

Figure A's Volume= 60

Figure B's Volume= 60 

Figure A's Surface Area= 104

Figure B's Surface Area= 248

So because the volumes are the same I knew it was not C or D, and then I solved the Surface Area for figures a and b and knew the correct answer is B.

Hope that helps. :)
