Answer 2

Here,

Time= 4 seconds= 4÷3600 hr( Here I converted seconds to hr you can also convert speed to m/sec)

Speed=45km/hr

Distance=?

Formula used=

Speed= Distance÷ Time

So, Distance= Speed× Time

Distance= (45×4)÷3600km

Distance=0.05km= 50m

So Distance travelled is 50m or 0.05km

Hope this will help.
