Question

Date

2) Jenny traveled to the lake and back. On the trip there she traveled 80 km/h and on the return trip she went 60 km/h. How long did the trip there take if the return trip took four hours?

Answer 1

Jenny traveled to the lake in 3 hours

Explanation:

on her way back from the lake,

Jenny traveled 60 km in an hour

let x km be the distance covered by her in 4 hours

x/60 = 4

x = 4 * 60 = 240 km

thus, the total distance on her way back from the lake is 240 km which she covered in 4 hours

on her way to the lake,

Jenny traveled 80 km in an hour

let x be the time taken by her to cover the complete 240 km

x = 240/80 = 3 hours

thus, on her way to the lake Jenny traveled in 3 hours
