ans question 14 plz urgent

Answer 1

$76 \div 4 = 19m \: per \: second \: into \: km \: per \: hr = 68.4 \: km \: per \: hr$

Answer 2

Distance = 76 m (Given)

Time = 4 seconds (Given)

Convert distance to km:

76 m = 0.076 km

Convert time to hour:

4 seconds = 4 ÷ 60 = 1/15 min

1/15 min = 1/15 ÷ 60 = 1/900 hour

Find the speed:

Speed = Distance ÷ Time

Speed = 0.076 ÷ 1/900 = 68.4 km/h

Answer: The speed is 68.4 km/h
