What is the speed of a car which covers a distance of 15 km in 20 minutes?

If the car travels 15km in 20 minutes, and 20 minutes are a third of an hour, so the speed per hour is : (15km * 3)/(20min * 3) = 45km/60min, as 60min is an hour so it’s equal to 45km/h.

How long does it take to travel 15 km?

2 Answers By Expert Tutors The distance equals 15km and the rate is 90 km/h. (15 km)/(90 km/h) = (1/6)h or “one-sixth of an hour.” Convert this to minutes. (1 h)/6 * (60 min/h) = 10 min. Thus, the answer is 10 minutes.

How long it rain will take to travel a distance of 200 km with a speed of 60 km per hour?

\”5. How long a train will take to travel a distance of 200 km with a speed of 60 km h-? Ans. 3h 20 min.

How do you convert from minutes to kilometers?

The conversion factor is 0.06; so 1 meter per minute = 0.06 kilometers per hour. In other words, the value in m/min divide by 16.6666666667 to get a value in km/h.

How far away is 20 kilometers?

How do you find the average speed of a moving object?

To derive a generalized expression to find the average speed, when the distance is the same: Let the two speeds be a kmph and b kmph. Let the distance traveled in each of the speeds be x km. Time taken to cover x km at ‘a’ kmph = x/a & at ‘b’ kmph = x/b. and the total distance covered = 2x.

What is the average speed of 45 km/h in 1 hour?

Hence it will cover 45km in one hr. Hence this is the speed. The average speed is 15 km / 20 minutes. You can convert that to whatever units you want – but you didn’t specify what units you wanted the answer in. If you wanted km / hour – you can multiply (15 km / 20 minutes) by (60 minutes / 1 hour).

What are the problems of speed time and distance?

Problems on Speed, Time and Distance: Usually, problems in this subheading cover finding one of the values, when the other two are provided. The important thing to note in such problems is that the units of all three quantities used are the same, i.e. if speed in km/hr, then distance will have to be in km and time in hours.

What is the ratio of the usual speed to the distance?

The distance = 60 km. Usual Speed = Distance ÷ Usual Time → 60/ (5/6) = 72 kmph. Speed on this occasion = Distance ÷ Time on this occasion = 60/1 = 60 kmph. The ratio between the usual speed to the speed on this occasion = 72/60 = 6/5 The ratio of the usual time taken to the time taken on this occasion = 50min/60min = 5/6.
