Question

Find the speed in the following cases:
(a) Distance = 70 km, time = 2 hours.​

Answer 1

Answer:

35 km/hr

Step-by-step explanation:

we know,

speed = distance/time

therefore,

speed= 70/2

=35 km/hr

Answer 2

★ Given :

• Distance = 70 km
• Time = 2 hours.

★ To Find :

• Speed ?

★ Required Knowledge :

The average speed of an object is obtained by the dividing the total distance travelled by the total time taken. i.e.

$\large\star{\boxed{\sf{\red{Speed = \frac{Distance}{Time}}}}}⋆$

Now, substitute the values :-

$⟶ { \sf{Speed = \frac{70}{2} }}$

$⟶{ \sf{ Speed \: = \: 35 \: km \: / \: hr}}$

■ Hence, The speed is 35 Km / hr.

________________________________

★ Distance :

• Length of path covered by a moving an object in the given time irrespective of the direction is called Distance.

★ Speed :

• The Travelled by the object in unit time.

• The SI unit of speed is m/s.

★ Time :

• Time is the duration of an event that is expressed in seconds.
