5. John takes 10 minutes to reach his school from his house. The distance of his school
from his house is 12 km. What is his speed during this journey?
(a) 2 m/s
(b) 2 km/min
(c) 20 m/min (d) 20 km/h
Answers
Answer:
12 km /10m = 12000 m /600s= 20m/s
Explanation:
speed is distance divided by time.
1000m=1 km
60 seconds =1 minutes
Answer:
The formula for average speed is distance over time, S=D/T. S is the variable we are solving for. You must convert the known units distance and time, if necessary, and input.
The formula for average speed is distance over time, S=D/T. S is the variable we are solving for. You must convert the known units distance and time, if necessary, and input.If we were to find Kilometers per minute we would setup the following equation:
The formula for average speed is distance over time, S=D/T. S is the variable we are solving for. You must convert the known units distance and time, if necessary, and input.If we were to find Kilometers per minute we would setup the following equation:S=1.2KM/10mins which equals .12KM/Min.
The formula for average speed is distance over time, S=D/T. S is the variable we are solving for. You must convert the known units distance and time, if necessary, and input.If we were to find Kilometers per minute we would setup the following equation:S=1.2KM/10mins which equals .12KM/Min.From there is an easy conversion to an hour. Multiply the previous result by 60.

John may have not been traveling at that exact speed the whole time but over the ten minutes that is his average speed.
