Solve Problems:

1) A running man crosses a bridge of length 500 meters in 4 minutes. At what speed he is running?

Speed in km/hr=^{25}⁄_{12}*^{18}⁄_{5}=^{90}⁄_{12}⟶^{30}⁄_{4}= 7.5 km/hr

2) A car running at a speed of 140 km/hr reached its destination in 2 hours. If the car wants to reach at its destination in 1 hour, at what speed it needs to travel?

6) Two boys start running at the same time in the same direction at a speed of 10 km/hr and 12 km/hr respectively. In what time they will be 8 km apart?

Both the boys are in motion so we will consider relative speed to find the time.

Relative speed = 12 – 10 = 2 km/hr

Distance = 8 km

Time =^{8}⁄_{2}= 4 hours (Option B)

7) A man walking at a speed of 8 km/hr covers a certain distance in 1 hour 45 minutes. If he runs at a speed of 10 km/hr, in what time he will cover the same distance?

Time = 1 hour 45 minutes = ^{105}⁄_{60}minutes =^{21}⁄_{12} hrs

Distance = 8 *^{21}⁄_{12}=^{168}⁄_{12}= 14 km

Time required to cover the 14 km at a speed of 10 km/hr = 14/10 = 1.4 hr

Time in minutes = 1.4 * 60 = 84 minutes (Option D)

8) A horse covers a certain distance in 40 minutes if it runs at a speed of 60 km/hr. At what speed the horse can cover the same distance in 30 minutes?

Speed of horse to cover 40 km in 30 minutes or ^{30}⁄_{60}hrs would be:

Speed = 40/(30/60) = 80 km/hr

9) A car moving at a speed of 75 km/hr covers certain distance in 2 hours. If its speed is reduced by 15 km/hr, in what time it will cover the same distance?

10) At his usual speed a cyclist covers a certain distance in 8 hours. When the speed of cycle is increased by 4 km/hr the same distance can be covered in 6 hours. Find the distance.
