Question

D. Numerical questions
1. Neeta travelled the first 3 hours of her journey at 60 km/h. She travelled the next 5 hours at
35 km/h. What was the total length of her journey? Now calculate what her average speed was.​

Answer 1

Answer:

Given,

Time 1: 3 hrs Speed 1: 60km/h

Time 2: 5 hrs Speed 2: 35km/h

Therefore,

total distance travelled in 3 hrs: 60×3= 180km

total distance travelled in 5 hrs: 35×5= 175 km

therefore, total length of her journey = (180+175)km = 355km

therefore, avg. speed= total distance/total time= 355/8= 44.375km/h

I hope this helps you
