Question

Topic speed anwser fast and detailed to be the brainliest if not reported

Answer 1

Given :

Speed from town A to town B = 90 km/h.

• Time taken = (1/4) h.

Speed from town B to C = 86 km/h.

Time taken = (2/5) h.

To Find :

Distance between town A and town

B.

Distance between town B and town

C.

Total distance he travelled.

Solution :

→ Speed from town A to town B = 90 km/

h.

→ Time taken = (1/4) h.

so,

→ Distance between town A and town B =speed * time = 90 (1/4) 22.5 km. (Ans.)

similarly,

→ Speed from town B to C = 86 km/h.

→ Time taken = (2/5) h.

SO,

→ Distance between town B and town C =

speed * time = 86 (2/5) = 34.4 km. (Ans.)

therefore,

→ Total distance he travelled = 22.5+ 34.4

= 56.9 km (Ans.)

Answer 2

Step-by-step explanation:

We can do this question by the formula :-

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

Case 1 :-

When the motorist took 1/4 hour and speed of 90 kmph

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

$\sf{Distance = 90 \times \dfrac{1}{4}}$

$\sf{Distance = 22.5 \ Km}$

(i) From town A to town B he took 22.5 km to travel.

Case 2 :- From Town B to town C:-

Here the motorist took 2/5 hours and 86 kmph.

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

$\sf{Distance = \dfrac{2}{5} \times 86}$

$\sf{Distance = 34.4 \ Km}$

(ii) From Town B to town C he took 34.4 km to travel.

Total Distance = 22.5 + 34.4 = 56.9 km

So, the (iii) Total distance taken is 56.9 km (approx. 60 km).
