Question

If a car A travels 180 km in 3 hours and a car B travels 140 km in 4 hours, then ratio of speed of car A to car B is ​

Answer 1

Answer:

Ratio=12:7

Step-by-step explanation:

$speed \: of \: car \: a = \frac{ \cancel{180} \: \: ^{60} }{ \cancel3}$

$speed \: of \: car \: b = \frac{ \cancel{140} \: \: ^{35} }{ \cancel4}$

Ratio=60:35

Simplify it

$\frac{ \cancel{60} \: \: ^{12} }{ \: \cancel{35} \: \: ^{7} }$

Ratio=12:7

Hope it helps you from my side

Answer 2

Answer:

Ratio of speed of car A to car B is 6 : 7

Step-by-step explanation:

Given  Car A travels 180 km in 3 hours ⇒ speed of the car = $\frac{180}{3}$ kmph

           Car B travels 140 km in 4 hours ⇒ speed of the car =  $\frac{140}{4}$ kmph

        from above data

       car A speed = $\frac{180}{3}$ = 60 kmph, car B speed = $\frac{140}{4}$ = 35 kmph

   ratio of the Car A to CarB =   car A speed : car B speed

                                                = 60 : 35

                                                 = 6: 7
