Answer:
15 km/h
Step-by-step explanation:
Leo takes 15 minutes to cycle to school at an average speed of 12 km/h. What speed will he have if he only takes 12 minutes?
15 minutes * (1 hour)/(60 minutes) = 0.25 hour
speed = distance/time
distance = speed * time
distance = 12 km/h * 0.25 hour = 3 km
He cycles a distance of 3 km.
12 minutes * (1 hour)/(60 minutes) = 0.2 hour
speed = distance/time
speed = 3 km/(0.2 hour)
speed = 15 km/h
Joe's dog has a mass of 28 kilograms. If you want to know about the solution, all you need to consider is this example: 1kg = 1000g. Therefore, the 28,000 gram dog is all-in-all 28 kilograms in terms of overall mass.
Nope you cannot write that in simplest form
It is not a monomial because the expression consists of more than one term.
