Question

A car travels at a speed of 45 km/h. Express this speed in m/s.​

Answer 1

Total time taken =1545hrs+2550hrs+1525hrs

=3hrs+2hrs+35hrs

=320hrs

∴ Average speed of the car =30×2045+50+25 

                                           =20120×3km/hr

=18km/hr.

${❥}\huge{\mathtt{{\purple{\boxed{\tt{\pink{\red{A}\pink{n}\orange{s}\green{w}\blue{e}\purple{r᭄}}}}}}}}$

■ SOLUTION ♣︎:-

speed=45 km/hr

so , First we have to convert km into m and hr into second.

now, we know that 1 km=1000m

and 1 hr=3600seconds.

Now, 45 km/hr=45×1000/3600=12.5 m/sec.

hope it helps you!!
