(a) What was the speed of Raj in the first five minutes?
(b) Both of them felt hungry and stopped at Ramji's Mithaiwala. For how long did they stop at the shop?
(c) How far from the start did Raj meet Suraj?
(d) How long did they walk together?

Answer 1

(a) Distance travelled by Raj = 500 m
Time taken = 5 min
= 5 $\times$ 60 s
= 300 s

∴ Speed = Distance/Time
= 500/300
= 1.67 m/s

(b) Time that they spent at the shop = 35 $-$ 15
= 20 min

They stopped at the shop for 20 minutes.

(c) Thousand metres far from the start

(d) Distance that they walked together = 1500 $-$ 1000
= 500 m

They walked together a distance of 500 metres.
