Speed in miles per hour is 45 mph.

Step-by-step explanation:

Since we have given that

Distance covered = 15 miles

Time taken to cover the above mentioned distance = 20 minutes

We need to calculate the speed in miles per hour ,

As we know the formula for " Speed " i.e.

Now, we will put the value of distance and time in the above formula:

Hence, Speed in miles per hour is 45 mph.

24miles/hour

Step-by-step explanation:

Speed is the change in distance of a body with respect to time.

Speed = Distance/tIme

Given parameters

Distance = 8miles

TIME = 20minutes

Convert minutes to hour

since 60minutes = 1hr

20 min = x

cross multiply

20 = 60x

x = 20/60

x = 1/3

Hence 20mins = 1/3 hr

Speed = 8miles/(1/3)hr

speed = 8 miles * 3/1 hr

speed = 24 miles/hr

Hence the object's speed in miles per hour is 24miles/hour

15 miles in 20 minutes.

there are 60 minutes in one hour.

Convert it from minutes to hour

there are 60 minutes in one hour.

Convert it from minutes to hour
