CBSE Class 9 Answered

A car travels with speed 30km /h for 30mins .and then with speed 40km/h for one hour find the total distance traveled by the car

Asked by darthvadermorningstar | 08 Aug, 2021, 12:47: AM
Expert Answer
Distance travelled = speed × time
 
Distance travelled with speed 30 km/hr = 30 km/hr × (30/60) hr = 15 km 
 
( since speed is given in km/hr , then time should be in hour )
 
Distance travelled with speed 40 km/hr = 40 km/hr × 1 hr = 40 km 
 
Total distance travelled = ( 15 + 40 ) = 55 km
