Help! I’m failing my math class and I haven’t really been paying attention So if you know the answer pleae tell me in the comments!! <3 question⬇️⬇️

Mark jogged 16.5 miles in 2 hours and Selena jogged 21 miles in 3 hours. Who ran at a faster rate?

this is marks

Speed

0.1167 miles per minute

7 miles per hour

this is selena

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
