Answer:

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

The object's speed in miles per hour is 24 miles per hour.

Distance = 8 miles

Time = 20 minutes = 20/60 = 1/3 hour

The speed of an object is calculated as:

= Distance / Time

= 8 ÷ 1/3

= 8 × 3

= 24

In conclusion, the object's speed in miles per hour is 24 miles per hour.
