Question

10. Identify the variation and solve. It takes 5 hours to travel from one town to the other if speed of the bus is 48 km/hr. If the speed of the bus is reduced by
8 km/hr, how much time will it take for the same travel ?

Plz give me step by step explanation.
I give 15 points for that.​

Answer 1

Answer:6hrs

Step-by-step explanation:

Distance = speed × time

So, 48 × 5 = 240km

Of speed is reduced by 8 ,

New speed = 48-8 = 40

So, 40 × t = 240

Which implies,

New time is 240/40 ---> 6 hrs

Answer 2

Step-by-step explanation:

Let the new time needed for the bus the travel distance d be t2.

t1 = 5 hrs

s1 = 48 km/hr

s2 = 48 - 8 = 40 km/hr

t2 = ?

d = speed x time

therefore

Variation:

d =s1 x t1= s2 x t2

48 x 5 = 40 x t2

t2 =  (48 x 5)/ 40

t2 = 6 hrs.
