Do you think the act of bus driver is correct? Which precautions one should take to avoid accidents on roads?
Answers
Answer:
99.6km/h
Step-by-step explanation:
Given -
The bus runs at the speed of 50km/h and to travel a certain distance it takes 42 min.
So, firstly we will find the speed of the car in 1min = 50/42 = 1.19km per min .
Now, the distance covered by bus in 42 min = 1.19 multiply by 42 = 49.8km
So, for covering 49.8km in 30min , we will divide 49.8 by 30 = 1.66 km per min
Therefore, the speed of the car for completing the journey in 30min will be ( 1.66 multiply by 60) = 99.6km/h
