a car travels 183.75 miles in 5 hours and 15 minutes. how fast did it travel. (put your answer in mph).

The answer needs to be in mph, or "miles per hour", so let's convert "5 hours and 15 minutes" to pure hours (with no minutes attached)

Since there are 60 minutes in an hour, this means that 15 minutes = 15/60 = 1/4 of an hour (quarter of an hour). I'm going to convert the fraction 1/4 into decimal form 0.25; use a calculator or long division to compute this.

Therefore,
5 hours and 15 minutes = (5 hours) + (15 minutes)
5 hours and 15 minutes = (5 hours) + (0.25 hours)
5 hours and 15 minutes = (5+0.25) hours
5 hours and 15 minutes = 5.25 hours



The car travels 183.75 miles (given) for 5.25 hours (value computed above). Use the formula shown below to find the speed or rate

speed = distance/time
s = d/t
s = 183.75/5.25
s = 35

Note: your math book might use "r" instead of "s".

So the speed of the car is 35 miles per hour
