Question

Rahul is travelling in a car from trichy to tanjore initially his car was travelling in uniform speed then after some time speed was increasing and decresing as he covered a total distance 120 km/4hours. .A) How will you help Rahul to calculate the average speed in km/h? B) Also calculate the average speed in m/s ?​

Answer 1

Explanation:

1. I travel total 120 km in 4 hours so my average speed will be 120/4= 30km/h

2. converting speed in m/s

30 km= 30,000meter

1 hour = 3600 second

so speed = 30,000m/3600s

= 8.33m/s
