A car moves with a speed of 40km for 15 minutes and then with a speed of 60 km for the nextb 15 minutes find the total distance covered by car in these 30 minutes
Answers
cars speed in first 15mins = 40km/h
distance = speed x time
= 40 x 15
= 600 meters
cats speed in second 15mins= 60km/h
d = s x t
= 60 x 15
= 900 meters
total distance tavelled in 30mins = distance travelled in 1st 15mins+ distance travelled in 2nd 15mins
= 600 + 900
= 1500 meters
in km
1km= 1000m
1m = 1/1000
1500m= 1500/1000
= 1.5 km ...............................
