Acar traveled 187 miles in 3 hours and 24 minutes what was the average speed of the car in miles per hour

3 hours and 24 minutes is 3.4 hours.

187 miles = 3.4 hours
divide both sides by 3.4

55 miles = 1 hour

The average speed of the car is 55mph.

Ithink the answer is: it is likely.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
