Question

A man walked steadily from 11.00am to 2.30pm at 5 kilometres per hour. how far did he walk

Answer 1

Time taken = 14 : 30 - 11 :00 = 3.5 hrs
Speed = 5 km /hr
Distance = time * speed 
= 3.5 * 5 
= 17.5 km

Answer 2

Taken time is from 11.00 am to 2.30 pm (14.30) = 14.30 - 11 = 3.30 hours

We know that D = S* T (D - distance, S - speed , T- time)

So, $D= \frac{5km}{h}*3.5h=\boxed {17.5 hours}$
