Question

please give the ans Q.3

Answer 1

let the distance she will cover in 7 h is = x


according to question

4h -------20km

7h -------- x


by cross multiplication , we get


4x = 140


x = 35 km


hence in 7h she will cover distance = 35km.

Answer 2

If priya covers 20km in 4hours Then she will complete x km in 1hour=
(20/4)=5/1
Therefore in 1 hour Oriya covers 5km .
Then in 7hours Priya covers y km=
7×(5/1)=35km
Hence Priya covers 35kms in 7 hours
