Help!! A high-speed train in Japan travels a distance of 300. kilometers in 3.60 x 103 seconds. What is the average speed of this train? (Turn the time into hours by using a unit conversion)

Question

60 min= 1hr

60s= 1min

Answer 1

You just need to set up your conversion such that seconds cancels out and you are left with hours.

3.60 * 103 sec *1hr/60min *1min/60sec

Give it a try

Is your expression 3.60 x 103 seconds or 3.60 x 10³ seconds?

Answer 2

X = 300 KM

t = 3600 seconds * (1 min/60 seconds) * (1 hr/60 minutes) = 1 hour

V = 300KM/1 HR = 300 KM/HR
