Question

A racing car covered 540 km in 3 hours 20 minutes. Find its speed in m/s.​

Answer 1

Solution

→ Distance cover = 540 km

→Time Taken = 3hrs 20min = 10/3 Hrs

Formula

→ Speed = Distance/time

→ Speed = 540/(10/3)

→ (540 × 3 )/10

→162kmh

→ Speed in m/s = ( 162 × 1000 )/( 60 × 60 )

→ ( 162000)/3600

→45 m/sec

Answer

→ Speed = 45m/sec

Answer 2

Question :-

A racing car covered 540 km in 3 hours 20 minutes. Find its speed in m/s.

Given :-

Distance covered = 540 km

Time Taken = 3hrs 20min = 10/3 Hrs

Formula to be used :-

Speed = Distance/time

Answer :-

Speed = 540/(10/3)

(540 × 3 )/10

162kmh

Converting unit :-

Speed in m/s = ( 162 × 1000 )/( 60 × 60 )

= ( 162000)/3600

= 45 m/sec

Final answer :-

Speed = 45m/sec
