Question

a bus cover a certain distance in 3hour 20minutes at the average speed of 45 km per hour how much time will it take to cover the same distance at a speed of 50 km per hour?​

Answer 1

Answer:

3 hours

Step-by-step explanation:

ATQ, the bus covers a certain distance in 3 hours 20 minutes at an average speed of 45 km per hour

Speed of bus = 45 km per hour

Distance covered in 1 hour = 45 km

Now: 3 hours and 20 minutes = 3$\frac{1}{3}$ hours

Distance covered in 3$\frac{1}{3}$ hours

= 3$\frac{1}{3}$ hours*45                                                                                = 150 km

The bus covers a distance of 150 km

Part 2

At an average speed of 50 km per hour, how much time will the bus take?

Speed = 50 km per hour

=> Time taken for 50 km = 1 hour

=> Time taken for 1 km = (1/50) hour

=> Time taken for 150 km = 150*(1/50) hour = 3 hours

The bus will take 3 hours to complete 150 km at an average speed of 50 km per hour
