Question

Find the ratio distance covered by a car and a cyclist when it is given that the car moves for 1.5hrs at 30 km/hr and cyclist moves for 1hr at 25km/hr?

Answer 1

Hi ,

We know that,


Distance = Speed × Time

1) speed of the car = s1 = 30 km / hr

Time = t1 = 1.5 hrs

Distance = d1 = s1 × t1

d1 = 30 × 1.5 = 45 km ------------- ( 1 )

2) speed of the cyclist = s2 = 25 km / hr

Time = t2 = 1 hr

Distance = d2 = 25 × 1 = 25 km --------- ( 2 )

Required ratio = ( 2) / ( 1 )

= 45 km / 25 km

= ( 5 × 9 ) / ( 5 × 5 )

= 9 / 5

Ratio = 9 : 5

I hope this will useful to you.

Answer 2

Answer:

9:5

Step-by-step explanation:

as we know the formula for distance=time*speed

so,

D1=T1*S2

D1=1.5*30

D1=45 similarly

D2 is 25

D1/D2

9:5
