Answers
Given : Sanjeev took 95 minutes to travel from home to office. The office is 7km from his home. On the way he spent 25 minutes at the tea shop.
To Find : at what average speed did Sanjeev travel in metres/minute
Solution:
Sanjeev took 95 minutes to travel from home to office.
On the way he spent 25 minutes at the tea shop
Total Time taken = 95 + 25 = 120 minutes
60 minutes = 1 hr
Hence 120 minutes = 2 hrs
Total Time taken = 2 hrs
Distance covered = 7 km
Average speed = Total Distance / Total Time
=> Average speed = 7/2
=> Average speed = 3.5 km/hr
1 km = 1000 km
7 km = 7000 m
average speed in metres/minute = 7000/120
= 700/12
= 175/3
= 58.33 meters/minute
appropriate equation for Average speed = 7 * 1000 / (95 + 25 )
