Answer:
40 mph <3
Step-by-step explanation:
Trust me, it isn't that bad. Miles per hour is what we would call a rate. In this case, this rate is made up of distance over time. They have given us this distance (1/4 of a mile) and time (22.5 seconds).
First off, lets convert our fraction to a decimal.
1/4 = 0.25
DistanceTime=mph
We must notice that out units for time are different than the rate. Therefore we must convert seconds to hours.
There are 60 seconds in a minute and 60 minutes in an hour.
60 x 60 = 3,600
22.5s×1hour3600s=0.00625hour
Now that we have the correct units, we can do our distance over time formula.
0.25mile0.00625hour=40mph
Sorry, I hope this is correct!!
