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.
