Question

a car moves with a speed of 40 km/h for 5 mins and after the speed changes to 60km/h for next 5 mins . Find the total distance travelled by car​

Answer 1

Total distance travelled by car is 8.333333

Step-by-step explanation:

According to the questions,

A car moves 40 km in a one hour,so the distance travelled by 5 mins,

then,

60 mins = 40 km

1 mins = $\frac{40}{60}$

So, the distance travelled in 5 mins,

5 mins = $\frac{40}{60}\times{5}$

           = 3.333333333333

After change the speed,car moves 60 km in one hour,

distance travelled by 5 mins,

60 mins = 60 km

1 mins = 1 km

then ,

5 mins = 5 km

total distance travelled by car ,

⇒ 3.3333333 + 5

⇒ 8.333333
