Answer 1

Step-by-step explanation:

1) 35000/300=350/3

Answer 2

Given, a person cover 35 km in 5 hrs
Solution,
=speed = distance/time
= 35km/5hrs
=7 km/h
A
Convert the speed into m/ min
We know that
1 km=1000m /1 hr=60 min
1000/60 m/ min
Convert 7 km/h into m/ min

7 km/h=7*1000/60
=116.66m / min
B
Convert the speed m/sec
We know that
1 km=1000m /1 hr=3600min
1000/3600 m/sec
Convert 7 km/h into m/sec

7 km/h=7*1000/3600
=1.944 m/ sec
