Question

Priyanka takes 30 minutes to cover a distance of 3 kilometres on a bicycle. calculate her velocity in units of kilometres /min,m/s and km/h.

Answer 1

solving stepwise we get the following answers.

Answer 2

Given

Priyanka takes 30 min to cover 3 km

on a bicycle.

To find

The velocity in Km/min, M/s, Km/h.

Solution

We can simply solve this mathematical problem by using the following mathematical process.

Now,

Time Taken by Priyanka = 30 min = 0.5 hrs = 1800 sec

Distance covered = 3 km = 3000m

Velocity (in Km/min) = $\frac{3}{30}$ = $\frac{1}{10}$ = 0.1 km/min

Velocity (in m/s) = $\frac{3000}{1800}$ = $\frac{5}{3}$ = 1.67 m/s

Velocity (in Km/h) = $\frac{3}{0.5}$ = 3 × 2 = 6 km/h

Hence the values of the velocity are solved
