Question

Rohit goes to school by car at 60km per hour and Manoj goes to school by scooty at 40km per hour.If they both live in the same locality,find the ratio between the time taken by Rohit and Manoj to reach school? PLEASE SOLVE AND GIVE SOLUTION

Answer 1

let the distance from school to homes of both be x(same locality)

1st case,
speed=distance/time
60=x/time
time=x/60--------(1)

2nd case,
speed=distance/time
40=x/time
time=x/40----------(2)

dividing (1) & (2)
x/60÷x/40
x/60×40/x(reciprocal of x/40)
2/3

therefore, the ratio is 2:3

Answer 2

Answer:2:3

Step-by-step explanation:

Speed1 of rohit's car = 60km (per hour)

Speed2 manjo's car = 40km (per hour)

Distance covered by

Both = 1km

Time taken=1/S1 1/S2 =1/60 : 1/40 = 1/60 ÷ 1/40 = 1/60×1/40 (cancellation done by 20 )

2/3 = 2:3 <----answer
