Answer 1

Question:

Lisa walks at an average speed of 6 km/h for 15 hours.

Dan completes the same distance in an hour. Calculate Dan's average speed.​

Answer:

`Speed = 90km/hr`

Explanation:

Given

Lisa:

`Speed = 6km/hr`

`Time = 15\ hr`

First, we calculate the distance covered by Lisa:

`Distance = Speed * Time`

`Distance = 6km/hr * 15\ hr`

`Distance = 90km`

So, Dan distance can be represented as:

`Distance = 90km` --- Dan completes the same distance as Lisa

`Time = 1\ hr` -- Time to complete the distance

Dan's average speed is:

`Speed = (Distance)/(Time)`

`Speed = (90km)/(1\ hr)`

`Speed = 90km/hr`

Hence, Dan's average speed is 90km/hr
