Answer:
12.5 miles per hour.
Step-by-step explanation:
There are 60 minutes in 1 hour so:
12 minutes = 12/60 = 1/5 of an hour.
So his speed in mph
= distance in miles / time in hours
= 2.5 / 1/5
= 2.5 * 5
= 12.5 miles per hour.
The speed in miles per hour is 12.5 miles/hour
How to calculate speed?
We define speed as :
Speed= Distance/Time
In other words, it is the distance travelled in a unit time
Here,
Distance=2.5 miles
Time=12 minutes that is 12/60 =1/5 hours
[tex]Speed=\dfrac{2.5}{1/5}[/tex]
Speed= 2.5*5=12.5 miles/hour
