complete the journey in 9 hours ?
Select one:
a. 35
b. 30
C. 60
d. 40​

Answer 1

${\mathfrak{\large{\underline{\underline{Answer:-}}}}$

40km/hr

${\mathfrak{\large{\underline{\underline{Explanation:-}}}}$

Given :

• Speed S1 = 60 km/hr

• Time T1 = 6

To Find :

• speed (km/hr) the bus must travel in order to complete the journey in 9 hours

Solution:

$\boxed{\sf{Distance} = \sf{Speed\times Time}}$

$\sf{D}=S1 \times T1$

$\sf{D}=60\times 6$

$\sf{D}=360km$

New time taken by car 9 hr

Speed => 360/9hr

Speed => 40km/hr

The new speed of car is 40 km/hr

∴ Hence option (d)40km/hr is correct

Answer 2

Answer:

40km/hr

Step-by-step explanation:

Given:

The bus takes 6 hours to complete the journey

bus travells at a speed of 60km/hr

Find:

The speed at which the bust must travel =?

Solution:

Speed = 60 km/hr

Time = 6 hours

Distance = speed x time

Distance = 60 x 6

= 360

since we have the distance value now we can find the desired speed

that is speed = distance / time

speed = 360/9

speed = 40

Therefore, the bus must travel at a speed of 40km/hr to complete the journey in 9 hours.
