Question

S=180 km/hr D=650 m, T=?​

Answer 1

Answer:

$speed = \frac{distance}{time}$

Given, Distance=650 m

Speed=180km/h

=180km/h ×5/18

=50 m/s

Therefore,

$Speed = \frac{ Distance }{ Time }$

•°• Time=Distance/Speed

= 650m/50m/s

=13 s.

Answer 2

$\huge{\bold{\underline{\underline{Question:-}}}}$

S=180 km/hr D=650 m, T=?

$\huge{\bold{\underline{\underline{Question:-}}}}$

S = 180km/hr = $180 \times\frac{5}{18} = 50\:m/s$

D = 650 m

T = ?

A.T.Q.

$speed = \frac{Distance}{Time}$

$speed \times Time = Distance$

$Time = \frac{Distance}{Speed}$

Substituting the values, we get

$Time = \frac{650}{50}$

$Time = \frac{\cancel{650}}{\cancel{50}}$

$\huge{\red{\boxed{\blue{Time\:=\:13\: second}}}}$
