Question 1201. If a man walks at 6 kmph, he can reach his destination at 9:00 am. However, he walks a little slower and reaches only at 10:00 am. If the distance to his destination was 12 km, at what speed did he walk?

5 kmph
4 kmph
4.5 kmph
3 kmph

Discuss Question

Answer: Option B. -> 4 kmph
IF HE TRAVELS AT 6 KMPH,
TIME TAKEN TO REACH = 12/6 = 2 HOURS BUT HE TAKES 3 HOURS.
SPEED = 12/3 = 4 KMPH

Question 1204. Asghar traveled from his house to his office at 10 km/hr and returned at rate of 9 km/hr. Rohit travelled through the same path both ways at 12 km/hr and took 10 minutes less than Asghar. What is the distance between Asghar’s house and his office?

3000m
7500m
3750m
7000m

Discuss Question

Answer: Option C. -> 3750m
AVERAGE SPEED FOR RAJ IS: V = (2*9*10)/(9+10) = 180/19 KM/HR = 50/19 M/S
AVERAGE SPEED FOR ROHIT = 12 KM/HR = 10/3 M/S
NOW, V = D/T
AS D IS SAME, V*T = CONSTANT.
LET, T BE THE TIME TAKEN BY ROHIT IN SECONDS. HENCE, TIME TAKEN BY RAJ IS (T +600)S
50/19 * (T + 600) = 10/3 * T
150*(T + 600) = 190T
T = 2250S
LET D BE THE DISTANCE BETWEEN THE HOUSE AND THE OFFICE
2D = 2250 * 10/3
2D = 7500 M
D = 3750M

Question 1206. An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in 5/3 hours, it must travel at a speed of:_________?

660 km/hr
680 km/hr
700 km/hr
720 km/hr

Discuss Question

Answer: Option D. -> 720 km/hr
DISTANCE = SPEED X TIME = 240 X 5 KM
NEW TIME =5/3 HR
HENCE, NEW SPEED = DISTANCE/TIME =240*5/5/3
=240×3=720 KM/HR

Question 1207. A car gives a mileage of 20 km per liter of petrol when driven at a constant speed of 50 kmph but the mileage decreases by 10% when driven at a speed of 70 kmph. How many km can the car travel with 12 liters of petrol if it travels a speed of 70 kmph?

Question 1208. A car travels 50% faster than a bike. Both start at the same time from A to B. The car reaches 25 minutes earlier than the bike. If the distance from A to B is 100 km, find the speed of the bike.

120 km
100 km
80 km
75 km

Discuss Question

Answer: Option C. -> 80 km
LET THE SPEED OF THE BIKE BE X KMPH. THEN THE SPEED OF THE CAR WILL BE 3X/2 KMPH. TIME TAKEN BY THE BIKE
T1 = 100/X TIME TAKEN BY THE BIKE
T2 = 100/(3X/2) T1 – T2 = 25/60 (100/X) – (100/(3X/2)) = 5/12 SOLVING THE EQUATION, X = 80 KMPH
