Question

time =20s
distance find
speed = 72 km/hr​

Answer 1

To Find:-

Distance

Given:-

Time↝20 second

Speed↝72 km/hour

Formula Required:-

Distance (d) = Time (t) × Speed (s)

To convert km/sec into m/sec multiply it by 5/18.

According to the question:-

Speed is in km/hr

∴ Distance will be in km

But, Time is in second

So, we have to find the Speed in m/sec

Then, Distance will be in m

Explanation:-

Speed = 72km/sec

Speed into m/sec = 72 × 5/18

= 5/4 m/sec

Distance ⇒ t × s

⇒ 20 × 5/4

⇒ 5 × 5

⇒ 25 m

Answer:-

Distance is 25 m

Time = Distance/Speed

Speed = Distance/Time

To convert m/sec into km/sec multiply it by 18/5
