Answer:
We know that,
Speed = Distance / time
Distance given = 100 kilometer
Time = 5/2 hours = 2.5 hours
First Speed of car = 100km/2.5 hours
First speed of car = 40 kilometer / hour
For second speed:
Distance = 30 kilometer
Time = 1/2 hour = 0.5 hour
Speed = 30 km/ 0.5 hrs.
= 60 kilometer/hour
Average speed of car = 40 kiloneter/hr + 60 kilometer/ hour
= 100 kilometer/hr / 2
Average speed of car = 50 kilometer/hour
Hope it helps you....
have a great day ahead
