Question

Solve it
a) speed= 15 km 1 hour , distance =75 km time = ?.…
​

Answer 1

Answer:

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

therefore here time=

$75 \div 15 = 5 \: \: hours$

Answer 2

☯ GiveN :

Speed = 15 km/h

Distance travelled = 75 km

$\rule{200}{1}$

☯ To FinD :

We have to find the time taken

$\rule{200}{1}$

☯ SolutioN :

We know the formula to calculate tge time taken.

$\large{\implies{\boxed{\boxed{\sf{Time \: taken = \dfrac{Distance \: travelled}{Speed} }}}}}$

★ Putting Values ★

$\sf{\dashrightarrow Time \: taken = \dfrac{\cancel{75}}{\cancel{15}}} \\ \\ \sf{\dashrightarrow Time \: taken = 5} \\ \\ \Large{\implies{\boxed{\boxed{\sf{Time \: taken = 5 \: hours}}}}}$

$\rule{200}{2}$

★ Additional Information :

★ Speed :

It is the distance covered by the particle in one second.

(i) It is a scalar quantity

(ii) Unit of speed is Meter/Second or km/sec.

☯ Types of speed :

(a) Instantaneous speed

(b) Average speed

(c) Uniform speed

(d) Non-uniform speed
