Question 977308: A car is traveling at an average speed of 18 km/hr
(i) Express its average speed in m/sec.
(ii) Find the distance it travel in 3 hours.
(iii) Find how far it travel in 25 seconds.
You can put this solution on YOUR website! A car is traveling at an average speed of 18 km/hr
(i) Express its average speed in m/sec.
Ans: 18(km/hr)*(1000 m/1 km)(1 hr/3600 sec)
(18*1000*1)/(1*1*3600)(m/sec)
----
= 5 m/sec
---------------------------
(ii) Find the distance it travel in 3 hours.
Ans: 3(18 km/hr) = 54 km
------------------
(iii) Find how far it travel in 25 seconds.
Ans: 25(5 m/sec) = 125 meters
