Answers
distance cover in one kilometre that is equal to 60 km per hour
distance in 40 minutes = 60/(1h) 60m
=1min/1h*
Answer:
The average speed of the car should be 80 km/hr to cover the same distance in 30 minutes.
Step-by-step explanation:
Let the distance be x km
We know Distance = speed × time
Distance = x km
Speed = 60 km/hr
Time = 40 minutes = 0.5+10 hour
Distance = 60km/hr × 0.5+10 hour
Distance = 60 × 0.5+10 km
Distance = 40 km
What should be the average speed to cover the same distance in 30 minutes?
Distance = 40 km
Time = 30 minutes = 30/60 hour
Average speed = to find out
Speed = 40 km/30/60 hour
Speed = 40 × 60/30 km/hour
Speed = 40 × 2 km/hour
Speed = 80 km/hr
The average speed of the car should be 80 km/hr to cover the same distance in 30 minutes.
Hope this answer help's you.
