A flatbed truck travels 144 miles in 5 hours. A semi-trailer truck travels 327 miles in 4 hours. A tanker truck travels 589 miles in 15 hours. Which truck has the fastest average speed?

The semi-trailer truck has the fastest average speed

Step-by-step explanation:

Let's recall that the formula of the average speed is:

Average speed = Distance/Speed

Now, we can calculate the average speed for each class of vehicle, as follows:

Flatbed truck average speed = 144/5 = 28.8 miles per hour

Semi-trailer truck average speed = 327/4 = 81.75 miles per hour

Tanker truck average speed = 589/15 = 39.27 miles per hour

Which truck has the fastest average speed?

The semi-trailer truck has the fastest average speed

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
