John took 60 minutes to cycle 25 kilometres after which he increased his average speedby 5 km/h. How long will it take him to cover the next 25 kilometres if he maintains the new average speed?

$\huge\blue{solution}$

Given:·

• Time taken to cover a distance of 25 km = 60 min = 1 hour
• Increase in speed = 5 km/h

______________________________________

To Find:·

Time taken to cover next 25 km 's

______________________________________

Concept:·

Speed = distance/time

Increased speed = x + 5 km/h

______________________________________

Calculation:·

Speed of John in his journey with cycle

Speed = Distance/time

[distance = 25km,time = 1 hour]

= (25/1)km/h

=25km/h______________________________________

Increased speed = x + 5 km/h

= (25 + 5)km/h

30km/h

______________________________________

Distance to be covered = 25km/h

Speed = 30 km/h

time = distance/speed

30/25

6/5

1.2 hour
