Question

How far will a person go if they jog for 2 hours at a speed of 12 km/hr? a) 6 km b) 0.5 km c)10 km d) 24 km

Answer 1

Speed = distance/ time

.

. . Distance = speed / time

= 12/2

= 6km

Answer 2

Given:

Speed = 12km/h

Time = 2 hours

To Find:

Distance travelled by a person who is jogging at 12km/h for 2 hours.

Solution:

We can solve the given numerical problem by the following method.

We know that,

speed(v) = distance (d) ÷ time (t)

We know the values of speed and time to be-

12km/h and 2 hours respectively.

To find distance, we can change the formula to-

d = v × t

We can multiply the terms as they have the same units.

d = 12 × 2

d = 24

The unit becomes→ km/h × h = km.

Hence, the distance travelled by a person jogging at 12km/h for 2 hours is 24km.
