Answer:
First, the velocity of a vehicle, if not known already, can be calculated by dividing the distance it covered by the time it allegedly made it.
Hence V=D/T. (1)
A car which travels at 60km/h means that within 1 hour, that car will run on 60 km. And for that matter, we consider that the car didn’t either stop nor change its velocity in the process.
We will do the same thing, assuming the car didn’t either stop nor change its velocity in the process, to find out the distance covered during particular periods stated in the question.
(1) V=D/T => D=VxT.
That means, to find the distance, we will multiply the velocity by the time spent on the road.
Here we go:
a)2 hours
Distance=(60 km/h) (2h)=>Distance (2 hours)=120 Km
b) 15 minutes
Distance=(60 km/h) (15/60h)=>Distance (15 minutes)=15 Km
Here, we made a conversion since our velocity is km/h, we convert the 15 mn into hour. Each hour has 60 minutes. So, we divide 15 by 60
Following the same reasoning, we will find Distance (30 minutes)=30 Km, Distance (3 hours)=180 km and Distance (half hour)=30 Km… Yes half hour=30 minutes
