Question

1. the distance between Delhi and lucknow is 500 km . how much time will a bus take to cover the distance at an average speed of 50km/hr.


2. A car moving at an average speed of 50km/h takes 5 h to reach its destination. find the distance covered.


please solve this it's of physics I request...​

Answer 1

Answer (i) :-

Given:-

• $\sf \: Distance \: between \: Delhi \: and \: Lucknow \: = 500 \: km$

• $\sf \: Average \: speed \: = 50km/hr$

To find:-

• $\sf \: Time \: taken \: by \: the \: bus \: to \: cover \: the \: distance \: at \: an \: average \: speed \: of \: 50 \: km/hr$

Solution:-

$\implies \sf \: Speed \: = \frac{Distance}{Time}$

$\implies \: \sf \: Time \: = \frac{Distance}{Speed}$

$\implies \sf \: Thus \: , \: time \: = \frac{500 \: km}{50 \: km/hr}$

$\implies \sf \: \: 10 \: h$

∴ Hence, the time taken by the bus to cover the distance at an average speed of 50km/hr is 10 hours.

Answer (ii) :-

Given:-

• $\sf \: A \: car \: is \: moving \: at \: an \: average \: speed \: of \: \: 50km/h \: takes \: 5h \: to \: reach \: its \: destination.$

To find:-

• $\sf \: Distance \: \: covered$

Solution:-

$⇝ \sf \: Speed \: = \frac{Distance}{Time}$

$⇝ \sf \: Distance \: = Speed \times Time$

$⇝ \sf \: Distance = 50km/hr \: \times 5h \: = 250km$

∴ Hence, the distance covered by the car is 250km.
