Question

a bus is traveling with a velocity of 80 km per hour. how much distance will it cover in 1.5 minutes ​

Answer 1

Answer:

2 kilometres

Explanation:

Given:

Speed of the bus with which it is travelling = 80 km/hr

80 km/hr = $80 \times \frac{5}{18} = \frac{200}{9} m/s$

Time = 1.5 minutes = 1.5×60 = 90 seconds

To find:

Distance travelled in 90 seconds with a speed of  $\frac{200}{9} \ m/s$

Distance = speed×time

Substituting the above values, we get:

Distance = $\frac{200}{9} \times 90$

Distance =  $200 \times 10$

Distance = 2000 metres

We know that 1000 metres = 1 kilometre

So 2000 metres = 2 kilometres

The bus will travel a distance of 2 km with speed 80 km/h in 1.5 minutes

Answer 2

Given

● Velocity of bus = 80 km/h

● Time taken = 1.5 minutes.

To find

● Distance covered by bus.

Solution

Here, velocity of bus = 80 km/h

⇒ Velocity (v) = 80 × (5/18) m/s

⇒ Velocity (v) = 22.222 m/s

⇒ Speed of bus = 22.222 m/s

Now time taken = 1.5 minutes.

⇒ Time = (1.5 × 60) s

⇒ Time = 90 seconds.

Using speed formula :

⋆ Speed = Distance/Time

⇒ Distance = Speed × Time

⇒ Distance = 22.222 × 90

⇒ Distance = 2000 m

⇒ Distance = 2000/1000 km

⇒ Distance = 2 km

∴ Distance covered by bus = 2000 m or 2 km
