Question

A car covers a distance at 30km/h for the first 3 hours and the covers another distance at 40km/h for the next 2 hours. Find the ratio of the distances travelled in the two cases. ​

Answer 1

Answer:

The ratio of distances is 9:8

Step-by-step explanation:

Speed = Distance / Time

Distance = Speed * Time

For the first part of the journey

Speed = 30 kmph

Time = 3 hours

=> Distance = 30 * 3 km

                   = 90 km

For the second part of the journey

Speed = 40 kmph

Time = 2 hours

=> Distance = 40 * 2 km

                   = 80 km

Therefore:

Ratio of distances in the two parts = 90 km / 80 km

                                                         =  9/8

                                                         =  9:8

I HOPE YOU WILL UNDERSTAND IT.
