Question

5. John takes 10 minutes to reach his school from his house. The distance of his school
from his house is 1.2 km. What is his speed during this journey?
(a) 2 m/s
(b) 2 km/min (c) 20 m/min (d) 20 km/h​

Answer 1

Concept Introduction: Motion in One dimension is the basic concept of Physics.

Given:

We have been Given: time taken is

$10 \: min = 600sec$

Distance given is

$1.2km = 1200m$

To Find:

We have to Find: What is his speed during this journey?

(a) 2 m/s

(b) 2 km/min (c) 20 m/min (d) 20 km/h

Solution:

According to the problem, we know speed is given as,

$s = \frac{d}{t} \\ s = \frac{1200}{600} = 2m {s}^{ - 1}$

Final Answer: The speed is

$2m {s}^{ - 1}$

Answer 2

Answer:

WE HAVE TO CONVERT IT INTO METER PER SECOND

Explanation:

1 MINUTE = 60 SECOND

10*60=600 SECOND

1 KILOMETRES = 1000 METER

1.2*1000 = 1200

SPEED = DISTANCE/TIME

SPEED = 1200/600

SPEED = 2METER PER SECOND
