Question

The distance between Anubhav’s school and his house is 45 km. He started from his house for school at 7:00 am and covered 30 km in 35 minutes. At this point, he met his friend and spoke to him for 5 minutes and reached school at 8:00 am. With what speed he covers the second part of the journey?

Answer 1

Answer:

45 km/h

Step-by-step explanation:

In the first part of the trip, he already covered 30 km so we can subtract that from the total distance

45 - 30 = 15

This means he has 15 km to go

He also took an hour, or 60 minutes, to get to school. We subtract the time spent of the first part and time spent talking to a friend from the 60 minutes

60 - 35 = 25

25 - 5 = 20

He took 20 minutes to cover the second part of the journey

Speed = distance/time

15/20 = 0.75

He covered 0.75 km per MINUTE

to find it in km/h, we just multiply the number by 60

0.75 x 60 = 45
