Distance between city A and city B is 330 km. If a train starts from city A at 8 a.m. and travels at 60 km/h towards B and another train starts from city B at 9 a.m. and travels at 75 km/h towards A. Then at what time will they meet?
If Sachin travels at 14 km/h instead of 10 km/h then we would cover 20 km more. What is the actual distance that he covered?
Let actual distance covered be x km.
And time taken to cover x be t hr.
Then, if Sachin is travelling at 10 kph so, we will have:
t = x/10 hours.
And, if Sachin is travelling at 14 kph then he would cover 20 km more than x so, we will have:
t = (x+20)/14 hours.
Since, both are equal we can write,
x/10 = (x+20)/14
or, x = 50 km
If you travel first 160 km of the journey at 64 kph and the next 160 km of the journey at 80 kph. Then what is your average speed?
Karan and Arjun are brothers and Karan is faster than Arjun. On Sundays they run 24 km. If the sum of their speed is 7 kph and the sum of time taken by them is 14 hr. Then what is the speed of Karan?
A biker starts with a speed of 70 kph and increases his speed every two hours by 10 kph. How long will it take to complete 345 km journey.
Can't be determined
A bullet train is travelling at an average speed of 100 kph and stopping for 3 minutes after every 75 km. Find the time it will take to cover 600 km journey.
6 h 18 m
6 h 24 m
6 h 22 m
6 h 21 m
If Jerry runs 200 m in 24 seconds then his speed is.
Convert 80 km/h into m/s.
If Sofia is driving at 37 kph uniform speed then find the distance she will cover in 8 hours.
Find the length of a bridge that Aamir crosses in 4 minutes driving at 54 kph.
Have fun learning :-)
