Question

Inna Marathon Varun runs 800 metre in 2 minutes 40 seconds what is his speed in metre per second​

Answer 1

Answer:

total distance travelled (S) = 800 meters

total time taken (t) = 2m40s = 2*60s+40s

= 160s

now,

speed (v) = s/t

=(800/160)m/s

=5m/s

Answer 2

Given:

Varun runs 800 metres in 2 minutes 40 seconds.

To find:

Speed of Varun.

Solution:

To determine the speed of Varun we have to use the below formula as follows-

We know that,

Distance=speed/time.

Distance is equal to 800 meters.

Time is equal to 2 minutes and 40 seconds.

We know that one minute is equal to 60 seconds. Hence 2 minutes 40 seconds is equal to 2×60+40=160 seconds.

Hence the speed of Varun is as follows-

Speed=800/160

Speed=5.

The speed of Varun is 5 meters/second.
