Romi and Sony are two brothers. They wanted to go to the library. Just as they were leaving, father stopped Sony. So, Romi started alone. A little while later, Sony ran and
caught up with Romi. Then after going together for some time they reached the library,
where they sat down and read some books. All this is shown in the form of a graph. Look
at the graph and answer the following questions:
a. What was Romi’s speed per minute while he
was moving?
b. For how long did father keep Sony waiting?
c. How long did Sony run before he caught up
with Romi?
d. How far from home did Sony finally meet
Romi?
