A car moves at a speed of 20km/h for 15 minutes and then at a speed of 60km/h for next 15 min. Calculate the total distance covered by the car.
Answers
20kmper h is speed so d is equal to speed multiply time so it wll be 20×1/4=15km. so td =10+5=15km
* Speed of the car for 15 min= 20 km/h or 20*15/60
=5 km/h
* Distance covered by the car= D= S*T
=5*15
=75 km
*Speed of the car for next 15 min= 60 km/h or 60*15/60
=15 km
* Distance covered by the car= D= S*T
=15*15
=175 km
Total distance covered by the car= 75 + 175 km
=250 km
