Question

A car is moving at speed of 50km in 1m and 30km in 2nd minute what is its average speed. Pls ans

Answer 1

speed of car at 1st min= 50 km per hour..
speed in metre per second = 50 ×5/18=250/18

similarly
speed of 2nd car in metre per second=
30 × 5 /18....=150 /18 m/s


adding both speed....we get 400 / 18 metre per sec

convert it to km / hour. =400/18 × 18/5=400 /5
=80 km /h

it is sum of both speed
so divide it by 2

80 / 2=40 km per hour...... this is the answer.......
